Movie from pdb file with 30 models of a conformational change.
by Evan Kantrowitz 02 Dec '24

02 Dec '24

Hi, Can someone give me help with a, I think, simple issue. I have a single pdb file containing 30 MODELS These 30 models correspond to a conformational change. Here is a portion of the Models list When I read it in,I see all 30 models showing in the view. What I want to do is make a movie showing these 30 MODELS one after the other. I have tried coordset and coordset slider but have not got it to work. Thanks Evan PS. This is what the image looks like with the 30 frames.It was generated from the A chain of pdb files 2e2n and 2e2q using the website ViewMotions (viewmotions.bc.edu <http://viewmotions.bc.edu/>). ----------------------------------------------------------------------------- Evan R.

Issue with Display of Hydrogen Bonds in Find H Bond Tool in Chimera
by GABRIELE SANTOS CEPINHO 12 Nov '24

12 Nov '24

Dear Chimera Support Team, My name is Gabriele Cepinho, and I am using Chimera version 1.17.3 for molecular docking analysis in my research. Recently, I encountered an issue with the Find H Bond tool that I have been unable to resolve, and I hope you may be able to assist me. When I use the Find H Bond tool to display hydrogen bonds between molecules, the generated image also shows polar interactions along with the specific hydrogen bonds. However, in the tool’s output file, I can clearly identify which interactions are true hydrogen bonds. My goal is to display only the hydrogen bonds in the image, excluding the polar interactions, but I have not been able to adjust the tool to achieve this. I have tried modifying the distance and angle parameters to restrict the display, yet polar interactions still appear alongside the hydrogen bonds in the visualization. I appreciate any guidance or recommendations you can provide regarding this matter. If there is any additional option to filter these interactions directly in the image, or if there is an update or specific setting available for the Find H Bond tool, I would be grateful to know about it. Thank you in advance for your attention.

Write out SeqRes entry
by David Bhella 07 Nov '24

07 Nov '24

Dear Chimera/ChimeraX team, I have a model for an asymmetric unit of a virus capsid that has three chains of the same capsid protein – but I am having trouble depositing my model in the PDB because it only has a seqres entry for one of the three chains (B). Whatever I do, chimeraX will only write entries for that chain. Is there a way to force chimeraX (or any other program) to write the seqres card for each chain correctly? Thanks D David Bhella Professor of Structural Virology Director, Scottish Centre for Macromolecular Imaging Associate Director, MRC - University of Glasgow Centre for Virus Research +44 (0)141 330 3685<tel:+441413303685> [signature_1350623625] [Logo, company name Description automatically generated]

ccp4 map from mtz
by Vitali James 31 Oct '24

31 Oct '24

Dear Greg, I just converted my mtz file in phenix to ccp4 maps. Chimera can open the mFo-DFc.ccp4 and 2mFo-DFc.ccp4 but how to fit pdb into the map?. Somehow the map does not appear as continuous crystals as in coot. Can you please explain how to align the pdb structure wuth the map. best James

About using Chimera(X) in articles
by Elaheh Kashani-Amin 30 Oct '24

30 Oct '24

Dear Chimera developers, We are a research and education group based in Iran and have been using Chimera(X) to teach our students about homology modeling and molecular docking. Recently, we discovered that our access to your website has been denied. Although we can access it via VPN, we would like to inquire if we can legally use Chimera(X) for academic purposes and cite it in our papers. We would greatly appreciate it if you could provide us with legal access to your products. Thank you for your time and consideration. Best regards Elaheh Kashani-Amin PhD, Molecular Medicine

which file is the Modeller executable on linux?
by Elaine Meng 30 Oct '24

30 Oct '24

Forwarding to chimera-users(a)cgl.ucsf.edu <mailto:chimera-users@cgl.ucsf.edu> so that somebody who knows the answer can respond. I don't know since I'm not on linux and do not use a local installation, sorry. That is the recommended address for asking questions about Chimera. Note that we do not actively develop Chimera any more. ChimeraX is recmomended instead -- it has essentially the same capabilities to interface with Modeller (local or web service) for loop modeling and for comparative modeling. The comparative modeling tool in ChimeraX is better than in Chimera, because it allows modeling multimers whereas the Chimera tool only allows modeling a single protein chain. Here are the help pages for the two ChimeraX tools, Model Loops and Modeller Comparative: <https://www.rbvi.ucsf.edu/chimerax/docs/user/tools/modeller.html> <https://www.rbvi.ucsf.edu/chimerax/docs/user/tools/modeller.html> Also, there is a different address chimerax-users(a)cgl.ucsf.edu <mailto:chimerax-users@cgl.ucsf.edu> for asking questions about ChimeraX.

Request for Example Data for Visualization
by lilei 27 Oct '24

27 Oct '24

Dear Chimera Development Team, I hope this message finds you well. My name is kevin, and I am currently working on a project that involves the use of UCSF Chimera for molecular visualization. I am reaching out to inquire if you could provide me with example data, particularly the "Example_FCTM" directory that contains the chimera_load.py script and other relevant files. Having access to this data would greatly assist me in understanding and utilizing Chimera more effectively for my work. Thank you for your time and assistance. I look forward to your response. Best regards,
