Problems with installation
by Roger Cole 01 Jan '24

01 Jan '24

Good Evening I wanted to asked about compatibility and installation issues. I am currently using a Chromebook with Linux Debian 11 (Bootstrap) and I am trying to get ChimeraX 1.7 installed onto it. I keep coming into errors when I try to run it by the way specified on the site. For info: " Download is a tarball of the chimerax application directory. Make symbolic link to executable in chimerax/bin/ChimeraX. Do not put on path. It may require additional libraries and/or older versions of libraries to be installed.

Recover unsaved ChimeraX session?
by André Graça 29 Dec '23

29 Dec '23

Dear all, happy Holidays! I am not very optimistic about this one, but I will just drop the question here and it may simply be that I am unaware of this function: I had a ChimeraX session crashing just when I was about to save it for the first time... is there any way to recover unsaved ChimeraX session, such as temporarily saved files? Thank you, André

PDB Conversion to Mol2 File Inquiry
by Joel Subach 28 Dec '23

28 Dec '23

Hello Chimerax, I hope you're well:). Towards the above subject, SwissParam has recommended UCSF Chimera to convert my pdb to a Mol2 File for SwissParam subsequent parameterization, however, I could not discover this webpage within your UCSF Chimerax Website? Thanks if you can clarify how I may generate this Mol2 via yout Chimera if able. Best, Joel 🚀

Re: How to save a sequence in an mmCIF file?
by Greg Couch 22 Dec '23

22 Dec '23

To answer the general question, ChimeraX doesn't yet have a way to set the full sequence for a mmCIF entity. See https://www.wwpdb.org/deposition/preparing-pdbx-mmcif-files for how to fix the mmCIF output from various refinement packages. For example, the Phenix has "mmtbx.prepare_pdb_deposition program to create a mmCIF file with the sequence". In this particular case, where the starting structure is an Alphafold prediction with atoms for every residue in the full sequence, you can get the correct sequence into the mmCIF output with the "bestGuess" option. See https://www.cgl.ucsf.edu/chimerax/docs/user/commands/save.html#mmcif. I'd also recommend, in your case, using the computedSheets option. In older ChimeraX's, you need to run dssp before using computedSheets to get the helix information. In recent ChimeraX's (daily build and 1.7 release candidate), computedSheets will also output the helix information if it wasn't present in the input. Adding a sequence with bestGuess can be deceiving of because missing leading or trailing residues, or gaps of indeterminate length. But in this case, you should be fine. -- Greg On 11/29/23 02:45, Guillaume Gaullier wrote: > *From: *Guillaume Gaullier via ChimeraX-users > <chimerax-users(a)cgl.ucsf.edu> > *Subject: **[chimerax-users] How to save a sequence in an mmCIF file?* > *Date: *November 29, 2023 at 2:45:31 AM PST > *To: *"chimerax-users(a)cgl.ucsf.edu" <chimerax-users(a)cgl.ucsf.edu> > *Reply-To: *Guillaume Gaullier <guillaume.gaullier(a)kemi.uu.se> > > Hello, > > Starting from an AlphaFold prediction, I refined a model against a map > with ISOLDE.
