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.

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

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

Unable to install
by Nadun Chanaka Karunatilleke R Wasala Mudiyanselage Vihare 15 May '20

Hi, I'm trying to install Chimera to my new mac & unable to do so. There's a message appears as "chimera can't be opened because Apple cannot check it for malicious software. This software needs to be updated. Contact the developer for more information." Can anyone suggest how i proceed from my side or do the program really needs any update? Thank you Nadun Nadun Karunatilleke Ph.D Candidate Dr. James Choy's Lab Department of Biochemistry Schulich School of Medicine & Dentistry The University of Western Ontario London, Ontario, Canada N6A 5C1
