Hi all, I am new to chimera is it possible to select chain and element for a structure? for instance select chain A and element carbons so they can be coloured red for example? thanks in advance. Jacob

Re: [Chimera-users] [Chimera-announce] new Chimera release (v1.10)

Dear Debasish Banerjee, There may have been changes in the ModBase website, or maybe even the UniProt website -- you would need to ask those developers. The ability of Chimera to show ModBase models did not change. Today looking at the ModBase website, I'm having a problem where it always says there are no models for some sequence, even when I know there are models. I don't know if this is the same problem you were having. I know there are models because I can fetch them using Chimera menu: File…Fetch by ID, choosing database: Modbase and entering a sequence ID (UniProt or other). The same can be done with a command, for example: open modbase:P33533 So maybe you can use that approach instead. Regards, Elaine ---------- Elaine C.

MatchMaker with betapeptides
by 러셀 29 Nov '14

29 Nov '14

Dear Chimera users, I would like to use the MatchMaker utility to superimpose a family of beta peptide conformers calculated through Xplor-NIH. Unfortunately, MatchMaker does not recognize these molecules and tells me the "chains are incompatible". Furthermore, I would like to specify that only certain residues in the beta peptides be used in the global alignment. I know how to match specific selections in 2 models through the Match utility using the command line (sel #0:1,2,3,4,5@CB,N,C,CA #1:1,2,3,4,5@CB,N,C,CA and then match sel) but I am unsure how to superimpose all of the models at the same time. For instance: models #1-20, residues 2-8, atoms C, N, CA, CB. If anyone could offer me help on the appropriate syntax I would be grateful. Thank you and best regards, Russell

centroids mutual distance etc. ?
by Marek Maly 29 Nov '14

29 Nov '14

Hello, is there any possibility to measure distance between the two centroids ? It is also possible to define somehow centroid which will be automatically updated when position of the atoms (which are represented by this centroid) are changed - e.g. for different frames from the Amber MD trajectory ? Thank you in advance for your comments, Best wishes, Marek -- Tato zpráva byla vytvořena převratným poštovním klientem Opery: http://www.opera.com/mail/

To Elaine Meng, May be I didn't explain properly. Most UniprotKB database entries have used Modbase in the 3D structure database section.

recent malfunction of reading ConSurf .chimerax files
by Alec Zander 28 Nov '14

28 Nov '14

Hello world of Chimera users, I use Chimera to visualize results from the ConSurf server. I ran some ConSurf jobs a while ago, downloaded the .chimerax files for offline viewing, and was happily using Chimera to do so. However, a few days ago, Chimera started hanging upon trying to load these very same files, and I get Chimera Launcher Error chimera exited abnormally; the exit code was: -805306369 I've gotten this same error for both Chimera v 1.9 and 1.10; Windows 7 Pro reports that pythonw.exe is not responding. I don't understand the cause of this error, and the Chimera debug executable seems to hang too. What to do? Best regards, Alex

Adding sugars to protein at specific amino acid glycosylation site
by T T 25 Nov '14

25 Nov '14

Dear Mr/Ms, Good morning. My name is Tommy from San Diego Biomedical Research Institute. I am currently learning to use the chimera software. Great work in creating a program for protein and DNA visualization. I have one question to ask regarding the subject above. Is there a way to manually add sugar component onto an existing pdb file? To be precise, I am currently working with HIV-1 envelope. I have the pdb files that features the structure of HIV-1 trimer Env. I wanted to add glycan at specific sites to show steric hindrance to antibody binding. Another question. Is there a way to superimpose 2 pdb files into one image? For example, I have one pdb file for HIV-1 Env and another pdb file for antibody. Can I "merge" these two pdb files as one image? Also, assuming that it is possible to "merge" two different pdb into one image, is there a way to rotate one protein without affect the orientation of the other protein? Any advice/tip is greatly appreciated. Thank you. Sincerely, Tommy
