Dear CHIMERA users, I am a PhD student in biostatistics and I want to run this algorithm in R. Can I have access to R code for CHIMERA? Thank you in advance

Molecular docking
by Schaf, Judith (2017) 27 May '20

27 May '20

Hi everybody, I have a quick question: when I analyse the results of a molecular docking assay (performed with SwissDock) on Chimera I sometimes see a green line between the protein and the ligand. Does someone know what this line represents? [cid:fc8bd8ab-4117-464a-b2fb-0f512e867f88] Thank you, Judith

Just choose the "all possible" option. <http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/editing/editing.h…> Or, you could use the "bond" command: <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/bond.html> The chimera-users(a)cgl.ucsf.edu address (CC'd here) is recommended for Chimera questions, unless private data are included. I hope this helps, Elaine ----- Elaine C. Meng, Ph.D. UCSF Chimera(X) team Department of Pharmaceutical Chemistry University of California, San Francisco

save images/scene - independent of chimera window
by Dominique Gutierrez 26 May '20

26 May '20

Good Morning, Is there a way to save an image independent of the chimera window size. When I reopened a saved session and saved an image from a scene it was not the same and it seems to be due to change in the chimera window. Best Regards. Dominique Gutierrez

Color by electrostatic potential
by Francesco Pietra 22 May '20

22 May '20

I was able to open with chimera 1.1.3.1 (linux) electrostatic-potential cube files generated from ORCA package and view them in colors (red lowest, blue highest potential). I can't remember how I succeeded and now, from chimera help, I am no more able. Only a single color. Thanks for putting me on the right way. chiendarret

Load AMBER trajectory from command line?
by Rodrigo Galindo-Murillo 20 May '20

20 May '20

Hello! I wonder if there is a way to load an AMBER topology/trajectory directly from the command line without having to go to tools->Md/ensemble-> MD movie, etc... For example, in VMD you can use: vmd -parm7 topology.parm7 -netcdf trajectory.nc I am NOT implying VMD is better than Chimera :) It will be just faster to be able to quickly load trajectories from the command line to save some time. Thanks! Rodrigo.

opening maps into an open session by clicking file in folder
by Dominique Gutierrez 19 May '20

19 May '20

Hello, I used to be able to open a map from any folder by clicking the file into an open chimera session but now it either opens in a separate chimera session or not at all. Is there a way to fix that? Best, Dominique

Comparing 2 similar structures
by Dmitry A. Semchonok 19 May '20

19 May '20

Dear colleagues, I want to compare 2 models that have some differences: the same subunits but repositioned, missing structures, etc. Is there a tool in Chimera that can: - Make a list of structure A (all components/residues). A list of elements in Structure B. - Compare and report the missing parts in structure B compared to structure A? Maybe also the differences in distances between the same helices in structure B compared to structure A? Thank you! Sincerely, Dmitry

Renumbering/reordering a session
by Dominique Gutierrez 16 May '20

16 May '20

Hello, Is there any way to renumber maps in a session so subsequent maps open together and in order instead of replacing the numbers of maps removed from the session? Best, Dominique
