Re: [Chimera-users] Get rotation between two views?
by Elaine Meng 10 May '22

Hi Zhen, Are you using Chimera or ChimeraX? Remember they are two different programs with many differences from each other. Chimera only has a "viewdock" command (no "view" series, but I'm not sure what you mean by that anyway). Also if you are having a problem like your window freezing, instead of sending a message to me or the list, it is better to report it by using menu: Help... Report a Bug (both Chimera and ChimeraX have this) and filling out the dialog. I hope this helps, Elaine ----- Elaine C.

Move model with associated map?
by Oliver Clarke 10 May '22

10 May '22

Hi all, Is there any way to apply the same transformation used by matchmaker for alignment to a map? I have two structures (map+atomic model) in different frames of reference. I would like to align one structure on the other, but also move the associated map in the same way. Is this possible? Cheers Oli

Error in using the "align chain sequences" tool in chimera

Dear all, After performing the structure comparison of 2 structures using the "MatchMaker" tool of the chimera software,I need to run an alignment of the structure sequences using the "align chain sequences" tool of the chimera.

Questions in ChimeraX comparing with Chimera
by Long Gui 27 Apr '22

27 Apr '22

Dear Chimera users, I have been recently transferring to ChimeraX from the conventional Chimera and I am currently struggling with two features existing in Chimera but not in ChimeraX. 1. How could I combine two or several different ChimeraX files? I have been doing in Chimera as I was opening new chimera files by "Files...Open...", this is a window pop-up as the following and if I click "No", the new Chimera will be added to the cold Chimera as the old one was not closed. However, when I performed the similar operation in ChimeraX, there is no such window and the new ChimeraX would REPLACE the old one. I wonder if there is a way (probably using command to open? but I did not find the correct open options.) to open the new ChimeraX without closing the old one? [cid:23bcde4a-3b02-4fc4-9b5e-7b034cd22a9f] 1. I am also working with tomogram slices and cellular segmentation. Previously, in Chimera I can set this Transparency value to 0 and the Plane of the tomogram will be totally opaque. Now in ChimeraX I have used the command "transparency #2 0" (#2 is the tomogram files) but it still look quite different from my previous images in Chimera. Is there a way to set it up in ChimeraX so it could look similar as before? [cid:1e2eb72a-f2e5-4c83-b4e4-81b881b9dc67] Thanks again and I am very grateful if any advice or help could be provided.

Re: [Chimera-users] Help and guidance on using chimera
by Tom Goddard 27 Apr '22

27 Apr '22

Hi Tommy, Sure those things can be easily be done. I'd encourage you to use ChimeraX instead of the old Chimera program. Also best to email questions to the Chimera mailing list (chimera-users(a)cgl.ucsf.edu <mailto:chimera-users@cgl.ucsf.edu>) or ChimeraX mailing list (chimerax-users(a)cgl.ucsf.edu <mailto:chimerax-users@cgl.ucsf.edu>). To delete a domain of a protein in ChimeraX that is say residues 151 to 375 of chain B delete /B:151-375 The command syntax would be different in Chimera. To add short linkers is more difficult and I will leave that question to Elaine to advise on the mailing list -- I am not the most knowledgable about how to do that.

Creating Bonds between Models
by Draven Houser 25 Apr '22

25 Apr '22

Hello, I am trying to build a structure in chimeraX that is a combination of several other known structures. To do this I need to be able to create bonds between different models in the software, but this doesn't seem to be possible for the moment. Can anyone suggest a workaround for this? Thanks!
