Clip surface but not atoms
by Pufall, Miles A 27 Jul '20

27 Jul '20

Hi! I’ve used Chimera for years (though not recently) and am switching to ChimeraX. I’m looking to display the ligand binding pocket with the ligand, and the tutorial you have is great. I generated this picture, which is really close to what I want. It shows the ligand, and the pocket, and I’m able to slice it with the interactive side view tool to get to this point. However, the left side of the ligand is slightly clipped. I’ve played with rotation and with moving the slice plane, but can’t find an orientation that shows the pocket so nicely (without any surface in the foreground) and not ligand clipping. My question is: is there a way to tell ChimeraX to clip the surface but not the ligand? Thanks!

Alternate locations
by Jeschke Gunnar 27 Jul '20

27 Jul '20

Hi ChimeraX team, very nice program and remote control scheme! Clear thinking, cool implementation. My question/suggestion is about alternate atom locations. ChimeraX knows about them. I load 1lcd info atoms /A:8@NE2 attribute alt_locs correctly responds: atom id /A:8@NE2 alt_locs A,B When I show /A:8@NE2 or I show /A:8 as sticks, only location A is displayed. When I retrieve atom coordinates, only location A is returned. Could you implement full handling of alternate locations (or am I doing something wrong here? I really tried a lot to find location B).

surface colouring by selected residues
by Oleksiy Kovtun 27 Jul '20

27 Jul '20

Dear ChimeraX community, I need to colour the surface by selected side chains to highlight an intermolecular contact. The command sequence: #select atoms on the buried surface. The selection works correctly: measure buriedarea #10/C:449-end withAtoms2 #9/A:449-end select true #make a surface. A new surface #10.1 is generated: surface #10/C resolution 7 #color surface yellow at selected residues. color #10 & sel yellow target s The last command does not result in surface colouring although reports "colored 1 surfaces" upon its execution. Where is a mistake in the colouring approach? I run chimeraX version 1.0 (2020-06-04) on Ubuntu 18.04. Thank you and best regards.

Cleanest Way to Install Daily Build
by Anderson, Jacob 24 Jul '20

24 Jul '20

Just wanted to reach out to see if there is a clean way to replace one's current ChimeraX with the daily-build (specifically Ubuntu). Is it best to uninstall/the prior and just install the desired version? Thank you for any thoughts! ~jacob

CryoET map problems
by Andrea Dallapè 21 Jul '20

21 Jul '20

Hi, I have an EM map -from a cryoET experiment- and I would like to use ChimeraX in order to fit the protein -the ribosome, in this case- in such EM map. I don't understand why the PDB of the ribosome I open in ChimeraX is far bigger than the EM map I have, and I don't really know how to resize them in order to have a fittable model. Could you suggest me a solution? Thank you for your help and attention, Andrea

Bond between two sequential residues
by Derek Harris 17 Jul '20

17 Jul '20

Hello, When I hide the backbone and choose to show side chain and base any sequential residues shown have a small line between the CA's. I can select them, but not delete them or hide them as an atom or bond, only hide sel, but when the selection they are a part of is hidden and reshown they reappear. I can also assign them as a selector and hide/show them, but also as soon as I hide and reshow the selection they are a part of they reappear and the designated selector for them is gone from the list. I want to retain the side chain and base appearance but lose these lines permanently. Any help would be appreciated.

Re: [chimerax-users] Using Vive controllers with webcam function in ChimeraX
by Tom Goddard 15 Jul '20

15 Jul '20

Hi Józef, The Vive controllers only work in VR mode. You could enable VR mode and just not put on the headset. The "vr roomCamera" command would allow showing the molecular graphics in the desktop window from a specific position which you would want to match your webcam's physical position in the VR space. And you will want to match the vr roomCamera field of view to the field of view of the webcam. Then you will have several problems. First, the hand controller cones won't line up perfectly with the video of the hand controllers -- there will be unpleasant lag. And without the VR headset on it will be very challenging to point at things. But you might as well put on the VR headset to solve that. Then it should work -- you can use the VR with webcam AR. This is just what I did with VR plus a depth sensing camera except that the depth camera also can blend the depth correctly.

Color electrostatic ValueError
by Maria Maldonado 14 Jul '20

14 Jul '20

Hello ChimeraX team, I was hoping you could help me with a python error I get when trying to use the color electrostatic command. I have my protein surface and my electrostatic map from Delphi in cube format. When I run “color electrostatic #1 map #2 palette -10,red:0,white:10,blue”, I get long error ending in “ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all() File "/programs/i386-mac/chimerax/0.91/ChimeraX.app/Contents/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/chimerax/map/data/gaussian/gaussian_format.py", line 120, in matrix if self.matrices == None: See log for complete Python traceback.” (I can send you the full error if useful.) I don’t get the error if I use a Delphi .phi file. However, the .phi files from this Delphi version have a bug that distorts the map, so the Delphi developers recommended using the .cube format instead. (The newer version of Delphi does not seem available for Mac at the moment.) Is the ValueError to do with ChimeraX or is it something to do with the .cube files? Do you have any suggestions as to how to solve this? Thank you very much for all your help, Maria

Dear ChimeraX developers, Hello! Thanks for this amazing tool, I enjoy every second of using it! I have a question about surface imaging: I have several subunits in the protein, and I would like to show surfaces of particular regions of different subunits. However, when one surface is above another, the lower one is not displayed no matter what the transparency value is. Is there a way to display both of the overlapping surfaces? Thanks in advance! -- With Best Regards, Anastasiya Oguienko

[chimeraX-users] to display cylinder and helical ribbon of one chain
by Yingyi Zhang 10 Jul '20

10 Jul '20

Dear ChimeraX Team, I have one model (pdb format), which contains multiple chains. Each chain (chain A for instance) consists of several helices. Is it possible to display ChainA in this manner - first two helices as cylinders but the others as ribbons? I tried to specify the residues, but it always changed the entire presence of the model, including the un-selected ones. Could you help me with this? I am still not very familiar with chimeraX.

When there are adjacent residues of the same type, does the PDB reader see a duplicate atom and generate a new residue? merge the residues? generate an error? I haven't tested the PDB reader, but a residue number helps it too. Learning to use mmCIF effectively will take time. Programmers should use the PDB's mmCIF Dictionary Suite to validate the mmCIF their programs output -- it won't validate completely (because it's for mmCIF files served by the PDB), but it will show where the mmCIF output can be improved. For more information about ChimeraX reading mmCIF, see https://www.rbvi.ucsf.edu/chimerax/docs/devel/bundles/mmcif/src/mmcif_guide…. ChimeraX's mmCIF reader tries really hard to show you the data exactly as it is specified. So if there's badly specified data, you'll be able to see it. Over time, we will improve ChimeraX's ability to handle underspecified data as developers start generating mmCIF files. But we don't plan to modify the mmCIF reader if we can help it. Adding code, to infer information that should be explicitly given in the mmCIF file, slows down the mmCIF reader for everyone. This is especially true for large structures with over a million atoms. -- Greg

Re: [chimerax-users] [Chimera-users] Chimera X - Windows 7 home premium
by Greg Couch 08 Jul '20

(This is a ChimeraX question, so sending the reply to the chimerax-users mailing too.) Looking at the image, the three gray boxes are icons for previously opened data files. To get an interactive 3D image, you would need to open an appropriate data file. If you type in the command "open 3rec" and press Enter/Return afterwards to open PDB model 3rec, does an interactive 3D image show up? If you can't get an interactive 3D image, then you probably need a newer graphics driver. I'd recommend going to the Lenovo support web site and installing a newer graphics driver. If the driver from Lenovo doesn't fix the problem, then you'll need to get one directly from Intel at https://downloadcenter.intel.com/. From the DxDiag.txt output, you have a 2nd generation i7 with HD Graphics 3000 driver version 8.15.10.2656. Lenovo has version 8.15.10.2274 from 6/9/2011 for your computer. On the Intel site, I see that version 15.28.24.4229 from 6/5/2015 is available. And you should know that we don't test ChimeraX on Windows 7, so technically you are on an unsupported platform. That said, we are unaware of anything that would prevent ChimeraX from running on Windows 7. However, with the age of your laptop, you should consider switching from Windows to Ubuntu (Linux). Intel is still supporting the Linux graphics driver for older systems.

ChimeraX bug report submission
by Nicco 08 Jul '20

08 Jul '20

The following bug report has been submitted: Platform: Darwin-19.3.0-x86_64-i386-64bit ChimeraX Version: 1.0 (2020-06-04 23:15:07 UTC) Description Hi, I'm trying to record a movie and the movie generated stops before executing all final steps. It's like the last frames are not recorded even when I see a very high limit. I feel like movie encode starts processing before it is called. For example these commands below are not present in the movie but the movie encode is called afterwards. # Select last interaction area select /F:370,375 /E:270,309,314 show sel atoms hbonds sel select clear # Final show turn x 15 60 rock 130 turn -y 15 60 rock 130 I'm a bit puzzled of why this is happening and I don't really now how to fix it. I attach the .cxc file with the set of instructions that I use to create the movie. Please consider that my experience level is beginner so there could be something that I'm doing wrong. Thank you!

Re: [chimerax-users] [Chimera-users] Difference in alignment of cofactor between Chimera and ChimeraX
by Elaine Meng 07 Jul '20

07 Jul '20

Hello Derek, You're welcome! Thought I should also mention that in matchmaker you can specify more than one pair of chains, i.e. use multiple pairs of chains for the fit. Which way is better depends on what you are trying to achieve: overall superposition of whole complex, or best fit of a single pair of chains. This multichain fit can be done in either Chimera or ChimeraX with a matchmaker command option. I'll use ChimeraX commands to illustrate: open 3u7q open 5n6y hide ribbon The ChimeraX log shows that 3u7q has four chains, two alpha (A,C) and two beta (B,D) whereas 5n6y has 6 chains, two alpha (A,D), two beta (B,E) and two delta (C,F). So perhaps you want to use all of the alpha and beta chains from the structures for the fit instead of only A with A. Now the trick is to figure out which alpha goes with which alpha and which beta with which beta. I might be lazy and first just try ABCD in 3u7q as pairing with ABDE in 5n6y and see if that looks right. I might also use coloring by polymer (figures out a color based on chain sequence) to make it clearer what's what. color bypolymer mm #2/A,B,D,E to #1/A,B,C,D pair ss <http://rbvi.ucsf.edu/chimerax/docs/user/commands/matchmaker.html> .... which actually looks right. The alphas and betas are colored the same within a given PDB structure but different between the structures, probably because of small sequence differences (something like one structure has a couple more residues on one end or the other; I didn't investigate, but it's expected). The Log reports: RMSD between 1026 pruned atom pairs is 1.314 angstroms; (across all 1783 pairs: 3.281) ...now to check the placement of cofactors: show ligand ~ribbon You can see a more symmetrical fit, with similar displacements on both sides. I hope this helps, Elaine > On Jul 7, 2020, at 9:39 AM, Derek Harris <derek.harris(a)aggiemail.usu.edu> wrote: > > Hello Elaine, > > Thank you very much for the rapid response. Following your commands, and seeing all the ligands, I now see what's happening. Just as you said; the proteins are each composed of two identical catalytic halves. In one half there is a nice alignment of the cofactors, but in the other half there is not.

how to turn molecule centering a specific atom in ChimeraX
by Shin Inchul 07 Jul '20

07 Jul '20

Hi, I was trying to turn molecule around specific atom. Since I am a beginner of ChimeraX, I would like to have some working examples in the command line. Without it, I have difficulties in applying the usage as appeared in the user guide. In PyMOL, mouse middle button click on a atom sets the centering on the atom then use rotate command. I appreciate all the supports provided. Thank you. Inchul

Re: [chimerax-users] session file sizes

To close molecular surfaces surface close #1 or just surf close If instead you do ~surface that hides the surface. I discourage use of these obscure "~" commands that Chimera used. Use "surface hide #1" or "surface close #1". If you just hide the surfaces they are still in the session file. You can also see the surface models in Model Panel by clicking the little triangle and the left of the model name to show submodel of your molecule. And you can choose those surface models and close them. Tom > On Jul 7, 2020, at 2:48 PM, Melissa Jurica <mjurica(a)ucsc.edu> wrote: > > That was my first guess, so I turned off the surface view.

label_seq_id in mmcif files for Chimera
by Marcin Wojdyr 07 Jul '20

07 Jul '20

Hi, I'd like to generate mmCIF files (using my own software) that can be read by Chimera. The problem is that sometimes I don't know the full sequence (SEQRES), so I don't know values for _atom_site.label_seq_id. If I skip label_seq_id entirely, the file doesn't load. ChimeraX gives warning: "Skipping atom_site category: Missing column 'label_seq_id'". If I set all label_seq_id values to null ('.') I get warning: "Unable to infer polymer connectivity due to unspecified label_seq_id for residue "ARG" near line 125" and all residues are disconnected. How should the mmCIF look like so that Chimera infers the connectivity in the same way as it does for PDB files? Cheers, Marcin

Re: [chimerax-users] [ChimeraX] #3464: partial surface mesh
by Elaine Meng 07 Jul '20

07 Jul '20

Hi Rory, There is no "hydrophobic surface" ... maybe you mean the molecular surface shown as solid (not dot or mesh)? Chimera's presets include "hydrophobicity surface" which is perhaps misleading, simply means the molecular surface colored by hydrophobicity. What exactly are you trying to do? Show protein as mesh surface and ligand as solid surface? You can definitely do it (or any combination of mesh surface on some atoms, solid on some other atoms) by opening multiple copies of the structure, as we said in previous messages. Then in the solid-surface copy, only show the parts of the surface you want as solid. In the mesh-surface copy, show the parts you want as mesh. For example, here is an example that shows H-ras as mesh surface with its ligand GCP as solid surface (image attached below), commands: open 121p open 121p surf #1 & protein surf #2:gcp surf style #1 mesh transp #1 50 surfaces color #2 gold surfaces hide solvent This can all be done with the menu as well, but it would take a lot more typing to enter that whole procedure. I Cc'd chimerax-users(a)cgl.ucsf.edu which is the recommended address for asking ChimeraX questions (for future reference). I hope this helps, Elaine ----- Elaine C.

color offset and surface type for mapping Electrostatic Potential
by Steve Chou 02 Jul '20

02 Jul '20

Hello everyone, I tried to map Electrostatic Potential (ESP) onto the molecular surface in ChimeraX v1.0 and PyMOL v2.1, but I found that the results were very different in these two programs. Therefore, I wrote to Elaine Meng and Tom Goddard for help. For your reference, I repost the ideals of our emails below. I first calculated the ESP with DelPhi v5.1 (a relatively old version) to get the .phi file (ESP). PyMOL commands for displaying ESP on the molecular surface are as follows: ------------------------------------------------ load 1ubq.pdb bg_color white remove resn hoh remove hydrogens hide line select heavy, name c*+o*+s*+n* show surface load 1ubq.phi, e_map ramp_new e_lvl, e_map, [-7, 0, 7] set surface_color, e_lvl, 1ubq set light_count, 1 set ambient, 0.5 set reflect, 0.2 ------------------------------------------------ ChimeraX commands for displaying ESP on the molecular surface are as follows: ------------------------------------------------ open 1ubq.pdb open 1ubq.phi hide #2 set bg white surface #1 color electrostatic #1 map #2 palette -7,red:0,white:7,blue material dull lighting simple ------------------------------------------------ In PyMOL, the colors (red/blue) are mainly on the residue (E/D, K/R) tips, while in ChimeraX, the colors are spread. Besides, the surface shapes are also slightly different in these two programs. See the image (left and middle panels) for the different colors and shapes. The color difference is caused by the color offset. The shape difference is also explained below. I changed the color offset to 0. Now the color looks similar in these two programs (left and right panels). The color offset (1.4 A) in ChimeraX gives a better idea of the possible charge interactions with other molecules. ------------------------------------------------ color electrostatic #1 map #2 palette -7,red:0,white:7,blue offset 0.0 ------------------------------------------------ The summary of the explanations from Tom: ------------------------------------------------ One idea I have for why PyMol shows redder tips is because ChimeraX is showing the potential 1.4 Angstroms away from the surface since that is about how far away a binding molecule would be. PyMol may be showing the ESP values exactly on the surface. You can try using 0 offset instead of 1.4 with the "color electrostatic" command "offset" parameter. https://www.cgl.ucsf.edu/chimerax/docs/user/commands/color.html#map ------------------------------------------------ The summary of the explanations from Elaine: ------------------------------------------------ As Tom mentioned, the rationale for the 1.4 A projection is that Chimera and ChimeraX show the solvent-excluded surface (SES), as opposed to the solvent-accessible surface (SAS). The SAS is approximately half a probe radius outward, and the SAS represents the closest possible approach of atomic centers of waters or ligands interacting with the protein, so the result is coloring by what values of the electrostatic potential (ESP) that such ligands would "see". The diagram in this page shows the relationships among SES, SAS, and probe. <http://rbvi.ucsf.edu/chimerax/docs/user/commands/surface.html> Possible reasons for difference in Pymol, if the ESP map itself is identical: (1) coloring by offset values or not. It has been my general understanding that when programs color the SES by ESP, the default approach is to color by the values one surface-probe radius outward. (2) shape/location of the surface. Is it an SES or SAS, or neither? Pymol surfaces often look more "melty" or smoothed to me than the SES in Chimera/ChimeraX. (3) the exact color-mapping, i.e. which colors at which values. Pymol ESP coloring often uses a duller-looking blue. ------------------------------------------------ All the best, Steve -- Steve Chou

hi, Is there a colorkey command in chimeraX (http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/2dlabels/2dlabels…>)? If it does not exist, is there any alternative other than using chimera and photoshop? Thanks Roberto

Is color command slower in ChimeraX than Chimera?
by Mungo Carstairs (Staff) 30 Jun '20

Hi, I'm testing driving ChimeraX (or Chimera) from Jalview, in particular colouring structures using the Jalview alignment residue colouring. Ideally this should perform well at scale for large numbers of structures and/or colours (for example a graduated colouring based on some property). I've noticed that ChimeraX appears to do this slower than Chimera. Is there a reason, or something I should do to make the command faster? Here's an example like for like comparison using the Chimera/X command line (also attached as a text file): Chimera 1.15 (build 42156) > open cifID:4zho cifID:5h92 cifID:1a70 cifID:4zhp > focus >

creating an annotated structure
by Melissa Jurica 30 Jun '20

30 Jun '20

Can you provide some guidelines for how one could create an annotated structure to share with colleagues? For example, I would like to annotate the cancer associated mutations of a protein, making it easy for someone to select and visualize the associated residue in a structure. Ideally, these annotations could be grouped and sorted. Even better, they could be linked to other resources. Thanks Melissa

Converting Chimera movie script
by Vid Sustar 26 Jun '20

26 Jun '20

The following bug report has been submitted: Platform: Linux-5.3.0-61-generic-x86_64-with-debian-buster-sid ChimeraX Version: 1.0 (2020-06-04 23:15:07 UTC) Description Hello! I have tried to adapt the cliping script from http://www.rbvi.ucsf.edu/chimera/data/movie-howto-mar2012/scripts/clip.cmd to work in ChimeraX (because my structure is too big, to be loaded properly in earlier Chimera) I tried to convert the old commands to the ChimeraX, but I get an error in the line "clip front -0.5 120": Expected a keyword Please advise me how to change the code to work with ChimeraX to create a movie or to simply save a series of images of cliped planes Best regards, Vid Sustar Log: UCSF ChimeraX version: 1.0 (2020-06-04) © 2016-2020 Regents of the University of California.

Morph cryoEM maps result
by Aritz Roa Eguiara 25 Jun '20

25 Jun '20

Dear ChimeraX team, This is probably a previously discussed topic but I have not managed to find it specifically anywhere. So I am trying to morph a couple of maps on ChimeraX using the volume morph command, but I do not get any slider as it happens with the atom model morphing (as far as I understand there is not option for that?) Also, once I do it I get a model that is called morph that if I run the movie is recorded but I cannot bounce or control any further, is it like a one time use command that then only leaves that model result of the last frame that cannot be used anymore? Best regards, Aritz

CIF writer renumbers residues
by Daniel Asarnow 23 Jun '20

23 Jun '20

Hi all, When I save a CIF from ChimeraX (while using ISOLDE), the warning "Not saving entity_poly_seq for non-authoritative sequences" is produced, and all the residues have been sequentially renumbered from 1. When there are missing residues, each segment has to be renumbered manually afterwards. Is there some way to avoid this with PDB or CIF inputs? Is it a bug? Best, -da

Changing to Menu_Mode:Add in Menu:Select seems not to have any effect on that. I think in Chimera1 named selections still could be added to the current selection using the „append“ selection mode.

Dear Emmanuel Moebel, I can't think of a simple way to make an index map from IMOD meshes, only a multistep process for each mesh object.

I hope this helps, Elaine =-=-= The following instructions are for Chimera: Each IMOD mesh object from the file is a surface piece. <http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/volumeviewer/imod…> You can specify that surface piece in a "mask" command as "sel" (after selecting it with the mouse) and specifying input map as "ones" to create a map that has values of 1 inside, 0 outside. Then you can scale the map by using "vop scale" to multiply values by a constant (e.g. for values of 2 or 3 instead): <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/mask.html> <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/vop.html#scale> Maybe if you did this for multiple mesh objects you could combine the results into one map with "vop add"; not sure how well this would work. <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/vop.html#add> Then you can save your index map as MRC using the Volume Viewer File menu or command "volume" <http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/volumeviewer/volu…> =-=-= The following instructions are for ChimeraX.

Re: [chimerax-users] [Chimera-users] Structure Minimization and Molecule Movement (ChimeraX-1.0)?
by Elaine Meng 20 Jun '20

20 Jun '20

Dear Ammar, For future reference, for ChimeraX questions it is better to use the chimerax-users(a)cgl.ucsf.edu mailing list instead of this one. We announced ChimeraX on both "announce" lists, however, because we thought Chimera users would want to know about it. (1) Moving only a subset of atoms. In ChimeraX, the way to move only a subset of the models or the atoms with the mouse is to assign the mouse to move only the selected models or atoms, then select the atoms of interest, and then move them with the mouse. For example, all of the icons in the "Right Mouse" tab of the toolbar represent different modes, and clicking an icon assigns that function to the right mouse button ( = trackpad + Alt on Windows, trackpad + command key on a Mac). Click the icon that looks like a blue sphere with arrows around it to assign the right mouse button to "move selected atoms." Then dragging with the right mouse button (or trackpad equivalent) will translate the selected atoms and additionally pressing Shift will rotate the selected atoms. Right Mouse icons and what they mean: <http://rbvi.ucsf.edu/chimerax/docs/user/tools/mousemodes.html> Similar between Chimera and ChimeraX: there are multiple possible ways to select the ligand, e.g. choosing its residue name from menu: Select... Residue... [residue name], or Ctrl-clicking on one of its atoms and then pressing the keyboard up arrow key to promote the selection to the whole residue. <http://rbvi.ucsf.edu/chimerax/docs/user/menu.html#select> <http://rbvi.ucsf.edu/chimerax/docs/user/selection.html> Although the Right Mouse icons only assign functions to the right mouse button, with the "mousemode" command, you can assign any of these functions to any mouse button alone or in combination with modifier keys. <http://rbvi.ucsf.edu/chimerax/docs/user/commands/ui.html#mousemode> (2) There is no minimize structure tool in ChimeraX currently. There are limited local "jiggling" calculations with the "tug" and "minimize" mouse modes but only for structures with only standard biopolymer residues and water, not ligands in general: <http://rbvi.ucsf.edu/chimerax/docs/user/tools/mousemodes.html> .... and more extensive molecular dynamics capabilities with the ISOLDE plugin for refinement/modeling into density maps: <https://isolde.cimr.cam.ac.uk/what-isolde/> I hope this helps, Elaine ----- Elaine C.

Dear All, I'm trying to run ViewDock from a script using the following command in a loop: runCommand("viewdock " + filename + " AutoDock") It works fine. However, the ViewDock window remains opened after reading each file. For large number of files it is not practical to close them manually. Is there a command to close the opened ViewDock windows to add to the script? Thank you for your help. Ibrahim

RMSD command in ChimeraX
by Hrvoje Rimac 19 Jun '20

19 Jun '20

Hi, I was wondering if there is a command in ChimeraX which calculates RMSD without first aligning the ligands (analog to Chimera command "rmsd"). The problem is that the order of atoms in the two pdb files is not identical, and in Chimera (1.14) the "rmsd" command (as well as the "match" command) compares the first atom to the first atom, the second to the second etc, regardless of their type (I checked this manually), so the calculated RMSD is very high. In ChimeraX this mismatching problem is resolved, however the only command I found was the "align" command which calculates RMSD after aligning the molecules (as "match" match does in Chimera). Is there a command that would calculate RMSD without aligning the molecules? This wouldn't be a problem if I had 2 ligands to compare, but since I have more than 900, it would be very time consuming to check and correct order of all atoms. P.S. I have attached the structures of the two ligands. The RMSD values I'm getting are: Chimera "match": 4.064 Chimera "rmsd": 4.147 ChimeraX "align": 0.252 The value I should get: 0.454 Best regards, Hrvoje Rimac Hrvoje Rimac, PhD.

ChimeraX: mmcif connectivity lost in some chains; OK in Coot
by Anderson, Jacob 18 Jun '20

18 Jun '20

Dear ChimeraX team, Thank you very much for your work on this great software. We use it daily, and without which it would be extremely difficult to articulate our science. I am touching base with a problem I am having after migrating from a pdb --> mmcif format.For context, I am running ChimeraX on Ubuntu 20.04 using a fresh deb install this morning: chimerax --version UCSF ChimeraX version: 1.0 (2020-06-04) © 2016-2020 Regents of the University of California. All rights reserved. To be explicit, my problem is entirely reproducible. Specifically, I have a file (attached) that when opened in ccpem's Coot v0.9-pre, has all the connectivity present. However, when I switch to ChimeraX, the connectivity of some chains are lost. A good example of this contrast on chain connectivity fidelity is chain LA and LB. (photo attached). I tried reading through the ChimeraX documentation on this CIF format,<https://www.rbvi.ucsf.edu/chimerax/docs/devel/bundles/mmcif/src/mmcif_guide…> but it remained not totally clear to me what is going awry in some chains but not in others. If you might have any insight on how to overcome this problem in chimerax, and allow all the chains to remain their connectivity, I would very much appreciate your thoughts/wisdom on the topic. ~Jacob [cid:0f6782e1-eb79-43db-93e8-0f8f44417fb3]

Dear Elaine, thanks for your help! Your example does not work for me on ChimeraX 0.93 (2020-04-03) both on a Windows and a Linux sytem. But after installing the new production version 1.0 the selection mode works indeed there on user defined selectors as expected, which is great!

Secondary Structure... Strand menu: Select... Define Selector... (I gave it the name "mystrands") menu: Select... Clear menu: Select... Structure... Ligand menu: Select... Menu Mode... Add menu: Select... User-Defined Selectors... mystrands Now both the ligand and strands are selected. Also works if I use commands for any of those steps. When you use the menu, the corresponding commands are echoed in the Log, and it actually works by running the commands, so it doesn't make sense that commands would work and the menu wouldn't. Tested in version 1.0. I hope this helps, Elaine ----- Elaine C.

selection modes

Dear all, is there a way to add user-defined selectors or named selections (command: name) to the current selection by choosing them from the Menu:Select or in the Basic Actions window? Changing to Menu_Mode:Add in Menu:Select seems not to have any effect on that. I think in Chimera1 named selections still could be added to the current selection using the "append" selection mode. At the moment adding named selections to the current selection works for me in ChimeraX just with the command line "select add" command. Many thanks for your help, Philipp Milkereit

Re: [chimerax-users] ChimeraX troubleshooting

Hi Joseph, Ok, it is complaining about a ChimeraX preference file C:\Users\Joseph\AppData\Local\UCSF\ChimeraX\ui-1 that saves your last ChimeraX window size (which is used when you start ChimeraX the next time), and saves any tools you added to the Favorites menu. It is supposed to be a text file but yours somehow contains all binary 0. Could you send us that ui-1 file, then delete it, and hopefully ChimeraX will start if there are no other problems. I will open a bug report and we will look at how this happened and probably put in some code so that if a preference file is unreadable ChimeraX will still start and just warn you about the corrupted file. You will get an email about that bug report and it would help if you could reply to that email with the ui-1 file as an attachment to help us debug the problem.

maximized on startup
by Anthony James Schaefer 17 Jun '20

17 Jun '20

Hello, Would it be possible to add an option for the ChimeraX app to be maximized on startup? I've got the window size set to 'last used' and I almost always maximize ChimeraX. With this combo, ChimeraX starts out the size of my screen, but not maximized. Thanks, Tony
