Markers from CMM
by Scott, Brandon L. 26 Oct '20

26 Oct '20

Hello all, When loading markers from a cmm file (example attached), is there a way to specify which submodel the marker goes to rather than it creating a new id? I've added the id_string to the cmm file when I created a new one which is the desired model. I hacked the following, which works, but there are hundreds of tracks so I would like to come up with an automated (and proper) way to do this. perframe "rename #2.$1 track_1 id #1.$2.2;" ranges 1,113 ranges 4,116 perframe "rename #2.$1 track_2 id #1.$2.3;" ranges 114,259 ranges 5,150 Brandon Scott, PhD CZI Imaging Scientist, Research Assistant Professor Nanoscience & Nanoengineering South Dakota Mines 501 E.

Hi Shaun, Apple will keep OpenGL graphics working well into the future. They switched to using their proprietary Metal graphics to run the macOS window system about 4 years ago, and deprecated OpenGL use, but that just means they aren't going to improve their OpenGL. Mac OpenGL drivers tend to crash when lots of graphics memory is used. We are considering using Vulkan instead of OpenGL maybe in a few years. Vulkan is an open standard and has been layered on top of Metal (called MoltenVK) and has native drivers on Windows and Linux. Also I have been testing Chimera and ChimeraX on the next macOS, called Big Sur, likely coming out in the next month. Both are working on Big Sur beta 10 released a week ago, although you need ChimeraX 1.1.1. We had to fix ChimeraX 1.1 on Big Sur because Apple changed how software finds the OpenGL library.

Hi Shawn, You are right that a MacBook with i5 CPU and 16 GB memory and Intel graphics will work fine for ChimeraX including making movies.

Greetings to all, When opening a new molecule, ChimeraX automatically apply a color to my molecule. I know how to modify the colors, which is very fun especailly using the command line but also very time consuming for multi-chain molecules. I would like to impose a coloring scheme for a model by default, that way everytime I open the model the coloring is the same for the my molecule. I guess one way is to use the function key but this would be limited to a mixumum of twelve molecules and is atom-spec dependent so not very practical. Is there a way to permently save the information, maybe in the pdb file header/footer, or somewhere else? Ramy Kazan PhD Student

Access to git repository
by Tomris, I. (Ilhan) 19 Oct '20

19 Oct '20

Dear sir/madam, At the moment I am utitilizing ChimeraX to render 3D images of lightsheet data I have obtained (see attachment of 3D render). It is a pretty nice software package, although there is something I would like to implement into chimerax. A bounding box/outline box with gridpoints on it to indicate the size of the rendered volume, additionally I would also like to implement a scalebar of some sort. Hence I was wondering whether I could get access to the git repository so I could attempt to use the "Outline box" already present and put grid points on it? [cid:ab15abd2-e188-42fa-ae88-eedbeae317dd] Kind regards, Ilhan

Re: [chimerax-users] Assistance: ChimeraX save scene

Hi Priyanka, Sorry for this late reply. I am copying the chimerax-users list (if you had sent your last email to the list, somebody else would maybe have answered you earlier; also a good idea to communicate through the list because all emails are archived and that sometimes enables people to find answers to their questions directly by searching the archives). Regarding you question about colors: in ChimeraX, the command "color list" will print in the log a list of colors with their names. Color names made of more than one word are listed twice: spelled with and without a space. I just checked that if you spell color names as they are listed by this command, it works. So, in your case, try spelling it "royalblue" with no space. Regarding your second question, I think this should work, but I am not quite sure what you are trying to do: volume zone #1 nearAtoms sel range 2 newMap true minimalBounds false in which #1 is your main map (so not necessarily #1 in your session, use the correct model number for your map as seen in the model panel) and sel is a selection of the atoms of interest (in your case "/A" for chain A), "range 2" is how many angstroms away from the model atoms you want to perform the map cut-out (I put 2 arbitrarily; try different values and use what you think is best for what you are trying to do), "newMap true" tells it to generate a new object for this map cut-out (it should show up in the model panel after you run the command) and "minimalBounds false" tells it to keep the same box size as your original map (if set to true instead, it will choose the minimal box size that encloses your map cut-out; not sure which one you need, but keeping the same box size should be safe). Once you have this, you can write this map cut-out to a file with the following command: save /path/to/your/new/map.mrc models #2 (replace #2 by the correct object identifier for your new map, as reported in the model panel).

Set transparency on DNA stubs
by Siyu Chen 16 Oct '20

16 Oct '20

Dear chimerax developers, I am writing to ask about an issue regarding to the transparency of DNA bases. I set the double strand DNA as stubs and colored cyan, and I wanted to set it as transparent (trans 70 tar c). However, it looks like only the DNA backbones become transparent, and the bases are still bright and solid. I even tried to throw in all possible targets into the 'trans' command (acrsbpfl) and got the same looking images. I am just wondering if this is because of the style or color that makes the bases look solid? Also, do you have other suggestions to get around this issue? Thanks in advance for your time and help! Best, Siyu Chen

Chnage Chain IDs
by Kazan Ramy (M.) 13 Oct '20

Greetings to all, In UCSF Chimera tools, there's an option to change chains ID/names. Unfortunately, I can't save my model under a cif format. While in Chimera X , I can save a model under a cif format but can't change the name of my chains, or at least I'm not able to find the command for that. My main goal is to have my model under a cif format with my new naming system, any idea on how I can solve this problem? Ramy Kazan PhD Student

Measure Motion / Blob Detection
by Scott, Brandon L. 09 Oct '20

Hello all, I had two questions: 1) I see there is now the option in measure area to ignore dusted objects, is it possible to have this feature in the measure motion as well? 2) For measure and mark blobs, Is there any way to use the output of the measure motion function to link the blobs since the triangle number changes in each frame, but following measure motion we know where it goes in the next frame.

Option Include non-water HETATM in Modeller Comparative
by Marta Martinez 09 Oct '20

Hi all, I am running a very simple example in Modeller Comparative (a small alignment including the template structure and the target sequence to model). Since the template harbors a HEME group, I decided to select the Advanced option "Include non-water molecules HETATM residues from template". However, no one of the retrieved models contains the HEME group. Does anyone know what could be happening?

right mouse zone selection labels
by Sarah Piper 09 Oct '20

09 Oct '20

HI ChimeraX team, I really like the feature in ChimeraX that creates a map clipping zone in the right mouse tools - zone with automatic labelling. However, the default labels are black background and yellow text, and only the residue 3 letter code and number. Is it possible to change these labels to a white bg and customise the labels to include e.g. the one letter code and chain ID? I tried to do this with the selection - labels tool but it did not seem to change it for the zone labels. Many thanks and keep up the great work :) Sarah

orientation

Dear chimerax experts, I have maybe a trivial question, I am willing to show a figure with several copies of the same protein, but when I move one copy of them using the "move x 10 model #1” etc command, they rotate upon probably the center of mass of all the models, such as when I separate all of them, they are rotated slightly different. I would like to show them in exactly the same orientation, is there a trick to move them in such a way that will be show in exactly the same orientation? Thanks a lot!

ensemble match; ensemble cluster; plotting RMSD
by Cristina Marino Buslje 25 Sep '20

25 Sep '20

Dear ChimeraX users, After a hole evening trying everything, reading every possible page, I can not do what I want that is superposing models of an NMR PDB (ej 20 models) all by all and compare their RMSD (a matrix if possible). And also compare this ensemble (NMR with 20 models) with another (let's say another NMR with 30-50 models). My chimeraX has not the option "Structure comparison" in the tools bars. The web manual doesn't give the commands needed to do so. Below is what is written in the manual but, as I said, structure comparison is not in my tools bar. " Ensemble Match, a tool in the Structure Comparison and MD/Ensemble Analysis categories". I know that there are tools to work with MD simulations (several conformers), but also can not find in the version install in my windows 10 computer. I know this is passible from chimeraX. Could you please help me find the solution? has anybody try this? Is very important for me to do it.

Re: [chimerax-users] [Chimera-users] Is RTX support planned?
by Tom Goddard 25 Sep '20

25 Sep '20

Hi Gökhan, We haven't considered working on raytracing in ChimeraX yet. What advantage do you think it would have? One that I can think of is that having multiples models with transparency could work correctly with raytracing. ChimeraX uses the same material for all surfaces now which defines how light bounces off it, how shiny it is. The ChimeraX material command controls those settings https://www.cgl.ucsf.edu/chimerax/docs/user/commands/material.html <https://www.cgl.ucsf.edu/chimerax/docs/user/commands/material.html> We may in the future allow different models to use different materials. ChimeraX also allows using textures on surfaces with the "color image" command, although good use cases are hard to come by: https://www.rbvi.ucsf.edu/chimerax/docs/user/commands/color.html#image <https://www.rbvi.ucsf.edu/chimerax/docs/user/commands/color.html#image> Generic 3D modeling packages like Blender, Cinema4d, Maya, ... work poorly or not at all with vertex colors which ChimeraX uses for multi-color surfaces like coloring a molecule surface by electrostatic potential. But sometimes people want to export those colorings from ChimeraX, for instance to print a 3D color surface and so they want the colors in a texture. So I have been looking at that use and will probably try to allow electrostatic and hydrophobic coloring to use a texture and to export as GLTF, OBJ, Collada or other 3D formats using texture colors in the next several months.

Hi ChimeraX team, I was wondering whether there is an option to make a mouse/cursor (or some sort of other pointer) visible when movies are recorded? E.g. When I want to point to my model or run simulations in Isolde and move atoms around, my mouse/cursor is not visible in the recording. Is it possible to keep the cursor visible in the recording, so that it becomes clear what was moved/pointed at in a movie recording? I hope the question make sense! Many thanks for all your work on this, awesome piece of software! Regards, Sarah
