Hello, after segmentation, I can save a selected region to a .mrc file, but the box size is changed. Can I keep the original box size (and the relative position in original map)? Thanks!

Problem with autodock vina in chimera
by De campos, Luana J 18 Jan '20

18 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?

Chimera X commands
by Andrew Waight 14 Jan '20

14 Jan '20

Hello all, I've been an exclusive Chimera user for over 15 years. I have been scripting a lot in python lately and am super excited to learn that ChimeraX is written in python3. I totally want to import some chimera functions into my programs. Problem is, the ChimeraX command syntax seems all new (i can't even really figure out how to select properly, is there a ChimeraX command index that I am missing and is ChimeraX for me? ChimeraX looks beautiful by the way. Thanks you guys are amazing! Drew

Fwd: Downloading HIV PDB 3j3q?

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.

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

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).

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

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.

Re: [Chimera-users] Chimera-users Digest, Vol 200, Issue 18

Hi, I ran into this Chimera/Delphi problem a few months ago (and discussed it with the Chimera/Delphi people). 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).

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 -----

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.

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

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.

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.

Contact_area Arguments
by Kevin Wang 06 Dec '19

06 Dec '19

Hi, I am using python to calculate contact area between 2 chains. My code is as follows p1, p2 = [s.surface_piece for s in openModels.list(modelTypes=[MSMSModel])] y = measure.contact_area(p1, p2, 2.5) However, this returns the error: TypeError: contact_area() takes at least 4 arguments (3 given) This is the function for contact_area def contact_area(p1, p2, d, color = None, offset = None, slab = None, smooth = False, optimize = True): What is the 4th required argument? Best, Kevin

pseudobond problem while writing mol2 format
by Palani, Kirubakaran 06 Dec '19

06 Dec '19

Hi All, I have a PDB file and want to convert the PDB to MOL2 format. The PDB has missing residues which is not a problem but when I write to MOL2 format it assigns the pseudobond and I really no need of it. I tried to solve it by checking the thread but I am not getting a clear solution for my problem. Last, I am doing this by using the script as I have >1000 PDBs to process the same way so the command line would be preferred. PS: I send you the molecule in PDB format as an example case.

Opening Amira segmentations

Unfortunately Chimera does not handle Amira segmentation files. Maybe we can add that to ChimeraX or next generation program. What kind of segmentations do you have? Are they surfaces?

Video about masking
by Krishan Pandey 06 Dec '19

Hi I am kind of new to Chimera and was wondering if there is a video tutorial about creating a mask in Chimera. I intend to use the mask for local resolution or multi body refinement. To experienced users this may be a novice question. I tried to search online but could find any. When I use volume eraser to delete part of EM map, it does not do anything, nothing is deleted. I am using Chimera 1.13.1 (build 41965). Any help is appreciated. Thank you Krishan Pandey

Fitting ligands/substrates to protein structure
by Jason Jeffrey Rodencal 05 Dec '19

05 Dec '19

Hello chimera users! I've been browsing the various tutorials for chimera and I've seen a lot of amazing models of proteins bound to DNA, ligands, etc. I have a pdb file for my protein of interest and its substrate, and I have the active site of the protein. I was wondering if there's any way of predicting how the substrate fits into the catalytic cleft. Is there some easy code or application that can do this in chimera or is this a far more challenging task than I appreciate? Thank you! Jason Rodencal Dixon Lab Stanford University

secondary structure restraints and crosslink restraints

Dear Chimera developers, I would like to perform homology modelling using Modeller in Chimera. At the moment I am using just distance restraints formatted like in the Chimera documentation (res1 res2 dist stdev). This file only contains crosslinking data. Is there a way to also include secondary structure restraints, that can serve as additional information during homology modelling? Or can I provide some were another file including this information separate from the crosslink information?

Undo option?
by Luca Pellegrini 27 Nov '19

27 Nov '19

I was wondering if there are any plans for an Undo option? I just managed to wipe a detailed view of an active site with lots of side chains, by selecting one more amino acid on the ribbon drawing and then picking by mistake ’show only’ rather than ’show’ (slip of the finger). ps: I found an old post on this in 2004, explaining that there is no such option, but perhaps the Chimera authors are open to changing their mind? After all, we are using Chimera to make ever more complex drawings.

Save pdb problem
by Rui Chen 26 Nov '19

26 Nov '19

Hello, I docked a ligand into a monomer, now I want to save a new pdb file. In the new pdb file, chian A will be docked monomer, chain B will be the chain B of homodimer. I already superimposed the two PDB files and deleted chain A of homodimer. I also used change chain ID to add chain IDs to the combined PDB file. However I got the following problems: 1. In my system, there are glycans (residue name: 0YB), *I cannot add chain ID to the glycans* (residue 209-216 belongs to chain A, residue 425-432 belongs to chain B) 2. In my system, I also have a small molecule docked in chain A, I realized only *the last line of the ligand was given a chain ID "h"*, is this a problem? 3. I want to *save these two PDB files as two chains, not two models* (actually it's a homodimer except for the ligand) 4. Can I manually *delete all the connections*? Looking forward to your reply. Best regards, Rui

Dear Wisoot Chanit, It is recommended to send Chimera questions to chimera-users(a)cgl.ucsf.edu (CC’d here).

It is easier to add wrong hydrogen atoms onto nitrogen heterocycles groups with other software, including openbabel, MGLTools, PyMol, etc. Now I want to add hydrogen atoms for a dataset, which contains more than 10 thousands ligands for virtual screening. And a great number of compounds in this dataset have nitrogen heterocycle groups. So I want to add hydrogen atoms for all these compounds by Chimera. When I try to run a script in Favorites > Command line by read a MOL, addh and delete the MOL in cycle. I found that the memory usage of Chimera keep growing although I have delete the previous MOLs. My question is: How can I avoid this problem while I want to handle numerous molecules with Chimera? If there is a way to run Chimera in a real terminal without run Chimera in graphic interface? Or Which bin file in Chimera_HOME can add hydrogen atoms for a molecule? Sincerely look forward to your reply. Thanks Best Shengfu Zhou 2019.11.19

How to draw a longer vector in visualization mode
by Byrd, Robert A. (NIH/NCI) [E] 20 Nov '19

20 Nov '19

I would like to draw a vector that would extend the connection of two points in a model. This would allow better visualization. The current status is a line that joins between the centroid of a plane of atoms to another atom that is above the plane. I would like to extend this vector out into space for say 5 or 10 angstroms. This would allow visualization of the direction relative to the remainder of the molecule. All that I have been able to do is draw a line between the centroid and the atom. This does not give the perspective to other parts of the overall scene. In the attached image this would be the red bar connecting the centroid of the purple plane to the green atom. How would one extend this out 5-10 Angstroms? Ideas? Thanks Andy Byrd

I am having problems mutating some residues with the 'swapaa' command. How do I mutate to 'A' or 'G' or 'I' for example? I always get an error that the rotamer library doesn't support it.

Programmatic trimming of PDB files based on alignment with reference structure
by Zachariah Schuurs 19 Nov '19

19 Nov '19

Dear Chimera Team, I have a reference protein domain and then a series of PDB files which all contain the same domain. I have programmatically been able to script an alignment of the reference to the same domain in the other files whereby he domain in the proteins of interest are isolated using the zone select method. This however leaves me with fragments and often misses some of the domain features of the interest proteins that occur outside of the specified zone. I am wondering if it is possible to write a python script that selects the area on the protein of interest by selecting the residues in the sequence alignment after MatchMaker is conducted. For instance - protein #0 is my reference protein, which is 150 residues long. My protein of interest contains the same domain as the reference, but is 500 residues long. Upon conducting MatchMaker and getting an output sequence alignment, the 150 residues of #0 (the reference) are selected, along with the aligned residues in the protein of interest. It is possible to select the residues in the sequence alignment window (as in the picture) but I wish to be able to script it. The selected 150 residues (or so) in the protein of interest are then saved as their own trimmed file. I have been able to write a python script for completing the MatchMaker etc, but I am not sure how to achieve the selection of residues in #1 based of the alignment with #0, or if it is even possible.

problem picking atoms in graphic window
by Wartell, Roger M 15 Nov '19

15 Nov '19

Hi, I have a peculiar but simple problem using Chimera [version 1.13.1(build 41965)] on a Windows 10 PC-computer]. Using it to model docking of small molecules to an RNA using autodock vina. This has worked fine. Recently wanted to measure distances by control-click on atom 1 and control-shift-click on atom 2 (picking the atoms in graphic window). Nothing came up in 'Structure Measurement' box when I 'picked' the atoms and clicked on Create except for it telling me I had to pick atom 1 and atom 2. If I hold the 'control' key of the keyboard down and move the mouse's hand symbol around an atom, the green outlined shape does not remain when I lift my finger from the mouse. On the right side of the bottom bar of the screen it says 'selection cleared' which disappears in a few seconds. When one holds both control and shift keys down and encircle the green shape around an atom, the outline remains. Control click in an empty area removes it, as it should. A postdoc in an adjacent lab who uses Chimera took a look and was puzzled since her downloaded version on her computer works fine in picking atoms etc. She also was puzzled since my mouse arrow when moved over an atom/residue did not show what residue it was, which apparently it should. We tried several pdb files (proteins and an RNA) and they all behave the same. We checked under Preferences that the matrix of radio buttons for my mouse's actions were set the same as hers. Is there some other preference setting I do not have set properly? Everything the mouse should be doing with regard to moving/rotating molecules is as expected, and the program otherwise appears to work fine. Any/all suggestions on solving this 'picking' atoms problem are most welcome. Thank you and the others at UCSF who have developed Chimera. Best Roger
