Problem during Residue interaction network generation
by Aditya Padhi 20 Feb '20

20 Feb '20

Dear Chimera users, I am using the StructueViz plugin of Cytoscape to launch Chimera and then loading the MD trajectory from Gromacs, where I need to generate the residue interaction network. After this step, when I click "apply" for displaying the interaction network in Cytoscape, it often shows "Importing Residue Network from Chimera", sometimes "getting data for attribute secondarystructure" and sometimes "getting data for attribute ishelix". Even after I wait for half a day, the message continues to show and I am not able to work on Cytoscape. I have even tried to reduce the number of frames of the MD trajectory to see if that helps, but that doesn't work even. Can anyone help me to how to resolve this problem? With best regards Aditya

Aligning a 2Fo-Fc map with the molecule in Chimera
by Miriam Gochin 20 Feb '20

20 Feb '20

The 2F0-Fc map was created with Phenix. I tried the "vop cover #1 atom #0" command but got the following error: NameError: global name 'step' is not defined File "/Applications/Chimera.app/Contents/Resources/share/VolumeFilter/cover.py", line 9, in map_covering_box g = volume.grid_data(subregion = 'all', step = step, mask_zone = False) Hoping to figure out how to make it work.

"subtract selected segment from map" from a specific map
by Dominique Gutierrez 20 Feb '20

20 Feb '20

Hello, Can I use the "subtract selected segment from map" in Segger tool to subtract the selected from a specific map and not just the map used for segmentation. In my case the segmented map is from a vop subtracted intermediate used to facilitate segmentation but I would like to quickly subtract several segments from the original map. Or is the only way to do that with vop subtract? Best, Dominique

Hydrogen labeling scheme
by Jack Fuller 19 Feb '20

19 Feb '20

Hello, I am part of a computational chemistry research group that frequently uses chimera to add hydrogens to pdbs. My coworkers and I have noticed that chimera uses several different labeling schemes for hydrogens. We have been unable to determine how chimera chooses which scheme to use. Is there a way to specify which scheme to use or to know which scheme chimera will choose? Thank you, Jack Fuller

SplitCommand python
by Healey, Joseph 17 Feb '20

17 Feb '20

Hi Chimera Team, I’m trying to reduce some overheads in one of my scripts part of which is coming from my use of `runCommand`. At the moment, I’m only using it for `split`, but I’d like to first test whether a model is already split to avoid unnecessary invocation. I’m aware the python equivalent of the command is buried inside chimera.SplitMolecule and the command split_command, however it doesn’t seem to be importable, as when I try: >>> from chimera import SplitMolecule Traceback (most recent call last): File "<pyshell#25>", line 2, in <module> ImportError: cannot import name SplitMolecule I’m getting the above ImportError. I can import other members of the chimera class (e.g. chimera.openModels or chimera.Molecule and chimera itself without issue). I’ve seen in the source code that SplitMolecule gets imported elsewhere, and it has the __init__ file, so I assume I’m just doing something stupid with paths or similar. That said, SplitMolecule is clearly within the main chimera modules directory, so I would have expected it to only be one ‘layer’ below `chimera` itself. Can you elighten me? I’m currently on chimera production version 1.14 (build 42094) 2019-11-13 06:05:13 UTC if that helps. If you could point me in the right direction to understand how the code will check for multiple chains and decide to split by chain, that would also be a massive help.

Docking
by Greta Hodo 10 Feb '20

10 Feb '20

Hi, I have a problem with the result of autodock Vina. When I load a molecule in “mol2” format and I use AutoDock Vina for docking, the docked molecule is altered. How can be possible? How can I solve my problem? I attach the photo of the real molecule [cid:C2748141-718F-40C4-8964-A212C52FDB1A] And this I how the molecule changes after the docking [cid:C1EDE285-2873-437D-A034-5BB2D031BD67] The 5-term ring becomes aromatic, while it should have only a double bond. ( this happens both if I save autodock vina result in “mol2” format and “pdb” format Hope you can help me!

Re: [Chimera-users] [chimerax-users] Reproduce exact view
by Tom Goddard 10 Feb '20

10 Feb '20

Hi Elaine, Alexis, You can change a model number by command. So if you replace model #3 with model #8 that you align to #3, then delete #3, then "rename #8 id #3" will change the model id of #8 to be #3. For the step of aligning #8 to #3, if they are aligned already then #8 would open aligned to #3 unless you had moved #3 in which case you could use "view position #8 sameAs #3". Of course if the new model has not been aligned to the old you may need to use the matchmaker command to align them.

Getting the matrices (view matrix), swapping out the model, and then reapplying the matrix may be the most exact way if the models are in the same coordinate system as each other. Otherwise you could open the new model, match or fit it to the one you wish to replace, then close the one you want to get rid of. That leaves you with different model numbers, however, so if it is important to get them the same you’d have to open the new model again, match it to itself, and remove the extra intermediate copy you’d opened first.

MD chimera bug
by Fabian Glaser 31 Jan '20

31 Jan '20

Dear Chimera developers, I think I have found abug in the MD movies tool in Chimera, when trying to use the Per-Frame command Script: When selecting residues > :1000 (which have a residue number > 1000) it does not select the the residue, since it adds to the residue number the frame number, for example see the figure attached, with this logic, and trying to apply the script, if the I try to select residue :1000 the script gives a mistake and this is because it tries to select residue frame + residue number (in this case 96000) which of course does not exist. The same sequence works perfectly if the selection is done outside the script Best, Fabian Best, Fabian Fabian Glaser PhD Bioinformatics Knowledge Unit - BKU The Lorry I.

conjugate moiety to protein PDB
by Michael Scott Bowers 30 Jan '20

30 Jan '20

Hi power users, I have 2 tasks that I hope you can help with. Both of these require conjugation of a moiety to multiple places on a large, multi chain protein. Command line solutions are fine. Task 1. Conjugate some group like a tosyl to selected cystine residues. There could be about 200 residues needing conjugation across 4 chains of a protein PDB file. Task 2. Conjugate a peptide chain to the N or C terminus of a multi chain protein PDB file. I am already familiar with build structure protein and smiles, but connecting models without severe steric hindrance is problematic. Also, given the number of needed conjugations, it would be great it I could do this via command line (or some other function that I am currently not aware of) so that the tosyl or peptide chains needing connecting do not have to be positioned prior to making the covalent bond. Much thanks to everyone in advance. Best, Scott

Auto-associate define attribute/render by attribute
by Healey, Joseph 24 Jan '20

24 Jan '20

Hi Chimera team, I’m working on a script to automatically render proteins in a complex by attributes (in this case, a number of scores obtained from different immunogenicity prediction algorithms). I currently have the script outputting attribute files as intended, but ideally I’d like to define the same attributes across all the chains of the model, which are made up of a number of different proteins. Is there any way for me to define the attribute file, or utilise some functionality to auto-associate an attribute file with all of the chains which have the correct sequence (similarly to how the sequence alignment input works at the moment?). Currently the attribute file is only using ‘numbered’ coordinates (:1, :2, :3…etc) , rather than the actual sequence. Since there’s no chain information in the attribute files, I’m not sure how I can go about connecting it to the right structure, other than manually at the moment?

Problem with autodock vina in chimera
by De campos, Luana J 17 Jan '20

17 Jan '20

Hi, I am using the option autodocking vina in chimera and I have a problem related to the docking results. I set up the docking parameters all correct and initiate the docking run. Apparently, everything goes well, I even receive a message in chimera saying that I can see the results in the directory chosen. However, when I use the option "ViewDock" I can not see the results and I get I message saying that the file .pdbt does not appear to be dock out. Also, the docking calculation goes really fast, not like before that I used to take some time. In my inspection of the .pdbqt file created in the directory from the docking calculation (using note pad) it just has the compounds and the flexible bonds, it does not have the energies of the complexes ligand-protein. Is there any way to correct this bug? Thank you very much.

Placing a model at 0,0,0?
by Divjak Maja 14 Jan '20

14 Jan '20

Hi there, I'm not sure this is possible, but what I would like to do is edit molecules in Chimera, position them at 0,0,0, save the PDB and then import the molecules into Maya, so that they are positioned at 0,0,0 in the viewport, instead of in some random position away from the work grid. I can actually edit molecules, then position them by eye in the Chimera viewport and save as PDB, which will position them near the grid in roughly the right orientation when imported into Maya. So what I'm looking for is a way of setting the molecules exactly to 0,0,0 in Chimera, so that they appear at 0,0,0 when imported into Maya. I'm not sure this is actually a valid concept in Chimera?

Depending on what you’re trying to do with this capsid, maybe you could try using ChimeraX instead of Chimera. It handles large structures much more efficiently, but it does not have the same set of features as Chimera. <http://www.rbvi.ucsf.edu/chimerax/index.html <http://www.rbvi.ucsf.edu/chimerax/index.html>> If you are just trying to get the atomic coordinates of the entire capsid, they are already in the file(s) you could download directly from the RCSB PDB without using any visualization program. <https://www.rcsb.org/structure/3j3q <https://www.rcsb.org/structure/3j3q>> Best, Elaine ----- Elaine C.

Placing a model at 0,0,0?
by Divjak Maja 13 Jan '20

13 Jan '20

Hi there, I'm not sure this is possible, but what I would like to do is edit molecules in Chimera, position them at 0,0,0, save the PDB and then import the molecules into Maya, so that they are positioned at 0,0,0 in the viewport, instead of in some random position away from the work grid. I can actually edit molecules, then position them by eye in the Chimera viewport and save as PDB, which will position them near the grid in roughly the right orientation when imported into Maya. So what I'm looking for is a way of setting the molecules exactly to 0,0,0 in Chimera, so that they appear at 0,0,0 when imported into Maya. I'm not sure this is actually a valid concept in Chimera?

Selecting multiple residues in one chain
by Yehuda Halfon 12 Jan '20

12 Jan '20

HI all, I want to select and color multiple residues in one chain. When I use select #1: 15, 18, 20 .B It select 15, 18 and 20 in all the chains. But when I use select #1: 15.B, 18.B, 20.B It select 15, 18 and 20 in chain B. Is there another way to select residues in one chain without adding .B after each one? It makes the script much bigger and less clean. Yehuda

Hello, I arrive a bit late to the discussion. After the Catalina upgrade, the open button in chimera is greyed out and I cannot open more than one file at any one time. Would anybody have any idea what is wrong? I have downloaded the latest build of chimera. Thank you for your help. Best, Chiara

However, the file you attached was not the ?.phi? file (electrostatic potential map) output from DelPhi. It was just the text output from the DelPhi program. If DelPhi runs successfully on your structure, it will create a separate file, with name ending in .phi, that is the electrostatic potential map. If by ?cube? you mean Gaussian cube grid, Chimera does read that format. <https://nam05.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.rbvi.u…> However, this format is handled simply as a map that is not necessarily electrostatic potential, so it would require more steps in Chimera to get the coloring you want.

The latest Delphi version that I tried (8.4) produced a cube format file which formally can be read and contoured in the Chimera volume viewer. I hated the way the electrostatic surface produced that way looked and abandoned it. Delphi v. 6 which I have (and which I think Elaine used 3 years ago) produced the good old .phi which is file properly displayed in Chimera . I think one can still get hold of V.6 from the Delphi distribution site. To avoid this mess I used the APBS interface of Chimera which worked fine and produced a nice, familiar style, looking electrostatic surface (see for example Fig. S10 in the supplementary of doi: 10.1093/nar/gkz604).

Re: [Chimera-users] Problem with DelPhi in chimera
by Elaine Meng 24 Dec '19

Hello, That sounds like a problem with your DelPhi setup, or you didn’t wait long enough for the calculation to finish. Sometimes it takes several minutes. Instead of DelPhi, you could try using PDB2PQR and then (on the resulting pqr file) using APBS. Chimera has interfaces to both of these: <http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/apbs/pdb2pqr.html> <http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/apbs/apbs.html> …or you can use their web server directly, outside of Chimera: <http://nbcr-222.ucsd.edu/pdb2pqr_2.1.1/> <https://apbs-pdb2pqr.readthedocs.io/en/latest/downloads.html#web-servers> I hope this helps, Elaine ----- Elaine C.

Hi, The Chimera v.6 that I used was the linux version NOT windows. The answer you got from the Delphi people sounds familiar to me which is why I switched to APBS interface on Chimera (works on both Windows and linux). The .dx file produced by APBS is read and contoured nicely by Chimera. If you need to ionize the structure, there is a Windows PDB2PQR executable as mentioned by Elaine (I understand that you're using Windows).

I do not know if it is possible to fix the phi file, sorry. The DelPhi files that Chimera can read are from the academic version of DelPhi, as mentioned here: <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/filetypes.html#esp> If you have some other version of DelPhi associated with a commercial package, maybe the format is different and Chimera does not know how to read it. Linked to the last section of this tutorial, there is an example DelPhi phi file (3eebB.phi) that Chimera can read: <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/tutorials/surfprop.html> I hope this helps, Elaine ----- Elaine C.

problems with multifit in chimera
by Nimit Jain 16 Dec '19

16 Dec '19

Hello I have recently been encountering problems with MultiFit within Chimera on both Ubuntu and Windows 10 (trace from reply log below--I get the same error on both operating systems). Even fitting with datasets that was working earlier in the year (~August-September) is not working anymore. My guess is that some changes have happened on the server that hosts Multifit. Could someone please try and reproduce the bug and let me know how I should troubleshoot this? I am trying to fit a single protein structure to an EM map and as I said, this was working earlier this year. I also tried downloading IMP on my Windows machine and using MultiFit from in there. This was running into some separate issues which I will not go into here since they are not directly related to Chimera. Thanks and best Nimit Trace from reply log: Application stderr ----- Traceback (most recent call last): File "/home/socr/a/yz/local/imp-repository/modules/multifit2/bin/generate_assembly_input.py", line 2, in <module> import IMP.multifit File "/home/socr/a/yz/local/imp-debug/build/lib/IMP/multifit/__init__.py", line 25, in <module> _IMP_multifit = swig_import_helper() File "/home/socr/a/yz/local/imp-debug/build/lib/IMP/multifit/__init__.py", line 17, in swig_import_helper import _IMP_multifit ImportError: libfftw3.so.3: cannot open shared object file: No such file or directory Traceback (most recent call last): File "/home/socr/a/yz/local/imp-repository/modules/multifit2/bin/create_all_surfaces.py", line 2, in <module> import IMP.multifit File "/home/socr/a/yz/local/imp-debug/build/lib/IMP/multifit/__init__.py", line 25, in <module> _IMP_multifit = swig_import_helper() File "/home/socr/a/yz/local/imp-debug/build/lib/IMP/multifit/__init__.py", line 17, in swig_import_helper import _IMP_multifit ImportError: libfftw3.so.3: cannot open shared object file: No such file or directory Traceback (most recent call last): File "/home/socr/a/yz/local/imp-repository/modules/multifit2/bin/generate_assembly_anchor_graph.py", line 3, in <module> import IMP.multifit File "/home/socr/a/yz/local/imp-debug/build/lib/IMP/multifit/__init__.py", line 25, in <module> _IMP_multifit = swig_import_helper() File "/home/socr/a/yz/local/imp-debug/build/lib/IMP/multifit/__init__.py", line 17, in swig_import_helper import _IMP_multifit ImportError: libfftw3.so.3: cannot open shared object file: No such file or directory Traceback (most recent call last): File "/home/socr/a/yz/local/imp-repository/modules/multifit2/bin/run_fitting_fft.py", line 2, in <module> import IMP.multifit File "/home/socr/a/yz/local/imp-debug/build/lib/IMP/multifit/__init__.py", line 25, in <module> _IMP_multifit = swig_import_helper() File "/home/socr/a/yz/local/imp-debug/build/lib/IMP/multifit/__init__.py", line 17, in swig_import_helper import _IMP_multifit ImportError: libfftw3.so.3: cannot open shared object file: No such file or directory Traceback (most recent call last): File "/home/socr/a/yz/local/imp-repository/modules/multifit2/bin/generate_indexes_from_fitting_solutions.py", line 2, in <module> import IMP.multifit File "/home/socr/a/yz/local/imp-debug/build/lib/IMP/multifit/__init__.py", line 25, in <module> _IMP_multifit = swig_import_helper() File "/home/socr/a/yz/local/imp-debug/build/lib/IMP/multifit/__init__.py", line 17, in swig_import_helper import _IMP_multifit ImportError: libfftw3.so.3: cannot open shared object file: No such file or directory Traceback (most recent call last): File "/home/socr/a/yz/local/imp-repository/modules/multifit2/bin/create_auto_proteomics_file.py", line 6, in <module> import IMP.multifit File "/home/socr/a/yz/local/imp-debug/build/lib/IMP/multifit/__init__.py", line 25, in <module> _IMP_multifit = swig_import_helper() File "/home/socr/a/yz/local/imp-debug/build/lib/IMP/multifit/__init__.py", line 17, in swig_import_helper import _IMP_multifit ImportError: libfftw3.so.3: cannot open shared object file: No such file or directory Traceback (most recent call last): File "/home/socr/a/yz/local/imp-repository/modules/multifit2/bin/align_proteomics_em_atomic_plan.py", line 3, in <module> import IMP.multifit File "/home/socr/a/yz/local/imp-debug/build/lib/IMP/multifit/__init__.py", line 25, in <module> _IMP_multifit = swig_import_helper() File "/home/socr/a/yz/local/imp-debug/build/lib/IMP/multifit/__init__.py", line 17, in swig_import_helper import _IMP_multifit ImportError: libfftw3.so.3: cannot open shared object file: No such file or directory Traceback (most recent call last): File "/usr/local/opal-local/bin/multifitWS.py", line 438, in <module> main() File "/usr/local/opal-local/bin/multifitWS.py", line 46, in main VersionMap[cf["version"]](cf) File "/usr/local/opal-local/bin/multifitWS.py", line 98, in v1_run asymWriteSolution(cf) File "/usr/local/opal-local/bin/multifitWS.py", line 411, in asymWriteSolution raise RuntimeError("Unable to find file combinations.output") RuntimeError: Unable to find file combinations.output -----

Regarding the UNDO issue raised by Luca
by Boaz Shaanan 13 Dec '19

Hi, Is not possible to install an automatic 'save session' at intervals determined by the user just as done in an MS word session? This at least may rescue the last operations. Following my own Chimera 'disasters' of this kind, I actually save session quite frequently when it becomes heavily loaded, particularly prior to a major new operation. My 2p.

Export of small molecule in ball-and-stick form to VRML
by Bickel, Aaron 13 Dec '19

13 Dec '19

Hi, I have successfully used Chimera many times to export 3D-printable STL files from small and large molecules. However, when I try to export a ball-and-stick small molecule scene to a file type with color information to print in color (such as X3D, OBJ, or VRML) the resulting file only has the sticks shown and none of the balls. This seems to be replicated across any molecule that I try to export. In general my process is to import a PDB file, visualize as ball and stick through the Actions menu, and then use the Model Panel Attributes menu to adjust the thickness of the balls and sticks to ensure a strong physical structure. Is there an additional step I am missing to export as VRML/X3D/OBJ? Thank you, Aaron

Volume Eraser
by Guo, Wangbiao 12 Dec '19

12 Dec '19

Dear all: I use the chimera (chimera-alpha-mac64) and input the room temperature FIB data (.mrc file), which is a huge algae cell (see below). I want to delete some map area, and used the Volume Eraser. But it can not delete but increase map. Is there any one knows how to fix it? I attached my screen record.

selection of specific bonds
by Damien Larivière 12 Dec '19

12 Dec '19

Dear All, My question is naive but I have difficulties to figure out how to do it with Chimera. I would like to select specifically the group of two atoms (C and O) formed in a carbonyl bond C=O for all, say, GLU residues of a protein. Is there a way, via a command line, to do it? Thanks for your help on this. Damien

Conference Announcement: Molecular Modeling Workshop, Feb 17-19, 2020 in Erlangen, Germany
by Harald Lanig 11 Dec '19

11 Dec '19

Dear list subscribers, we are very delighted to announce this year’s “34th Molecular Modelling Workshop (MMWS)” (http://mmws2020.mgms-ds.de) that takes place on Monday 17th to Wednesday 19th February 2020 at the Friedrich-Alexander-University in Erlangen, Germany. The MMWS has a long history of giving young scientists (especially graduate students) the opportunity to present their work and dive into discussions with each other and the "older experts" of the field to gain valuable feedback from academic as well as industrial colleagues. Oral and poster contributions are welcome from all areas of molecular modelling – from the life sciences, computational biology and chemistry, cheminformatics, to materials sciences. Starting with the scientific program on Monday after lunch should allow to avoid travelling on weekend keeping the expenses at a minimum. Once again the location changed - back to the roots we are now back again in the Organic Chemistry building at Henkestrasse 42. A hearty workshop dinner and a traditional joint evening in Erlangen’s Steinbach-Bräu brewery complement the scientific program. The workshop is organised by the German Section of the Molecular Graphics and Modelling Society (MGMS-DS e.V.). ####### Pre-conference Schrödinger workshop ####### For the third time at our Molecular Modeling Workshop, Schrödinger is offering a pre-conference workshop entiteled "Structure-based Drug Design using the Schrödinger Suite". If you are interested in participating at the software session, please checkmark the corresponding field upon filling the registration form. Please note that this event is taking place at the CCC in Naegelsbachstrasse 25. ####### Plenary Speakers ####### We are very happy to announce that five outstanding researchers accepted our invitation to present a plenary lecture at the Modeling workshop: Petra Imhof, Berlin “Recognition and specificity in protein-DNA interactions - insight from molecular simulations” Pavel Jungwirth, Prague "Electrons in Liquid Ammonia and in Water: From Blue Electrolytes to Bronze Colored Metallic Solutions" Barbara Kirchner, Bonn "Insights into ionic and molecular liquids and their interfaces from computational chemistry" Charles Laughton, Nottingham "Enhancing conformational sampling with machine learning" Birgit Strodel, Jülich "Modelling peptide aggregation influenced by in vivo conditions" ####### Poster and Lecture Awards ####### As in the past years, there will be two poster awards of EUR 100 each and three lecture awards for the best contributed oral presentations: 1st winner: Travel bursary to attend the Young Modeller's Forum in London, UK, plus a speaker slot option at YMF (travel expenses are reimbursed up to EUR 500) 2nd winner: EUR 200 travel expenses reimbursement 3rd winner: EUR 100 travel expenses reimbursement Only undergraduate and graduate research students qualify for the poster and lecture awards. ####### Registration and poster/talk submission ####### Submit talks and/or poster titles via the registration form accessible on the workshop website https://mmws2020.mgms-ds.de/index.php?m=register The deadline for all submissions is January 24th, 2020. ####### General information ####### Website http://mmws2020.mgms-ds.de will provide all necessary information about the meeting. We are looking forward to meeting you in Erlangen! - Christof Jäger, Scientific Committee Workshop Organisation 2020 - Harald Lanig, Chairman of the MGMS-DS e.V.
