Coloring proteins by Ca rmsd when they have different sequences
by Vorländer,Matthias Kopano 05 Jul '23

05 Jul '23

Hi all, I would like to color proteins by the Ca-RMSD after aligning them, and found the Youtube tutorial on how to do this for proteins with identical sequence. However, I would like to compare structures from different species, as for example done in Figure 2 in this paper https://www.sciencedirect.com/science/article/pii/S0959440X16302408?via%3Di… . Is this possible in ChimeraX? Many thanks, Matthias

Extract settings/parameters from a chimerax cxs session file
by alan.cheung＠bristol.ac.uk 04 Jul '23

Hi All - apologies if this has been answered before, couldn't find it with search. I have a session file with very nicely formatted views/lighting/graphics settings, but i'd like to duplicate them for another (new) session. I can't remember what i set! And it's not in the log. Is there a way to get ChimeraX to return these values (or indeed, all parameters) for the current session? I imagine this might be useful generally too. Alan

Re: [Chimera-users] Opening MTZ files on Mac OS

Hi Natalie, This is a ChimeraX question, although sent to the chimera-users list -- although unnecessary this time, for future reference please send chimeraX questions to the chimerax-users(a)cgl.ucsf.edu list CC'd here (we try not to confuse Chimera users with ChimeraX answers and vice versa). The instructions of how to open MTZ files with ChimeraX are here: <https://rbvi.ucsf.edu/chimerax/docs/user/commands/open.html#clipper> "Opening an MTZ file requires specifying an already-open atomic structure with the structureModel option..." with example command, etc. I hope this helps, Elaine ----- Elaine C.

I read somewhere that you need to download the Clipper plug-in. I went ahead and installed that (although I am not sure that I was successful) and am still struggling to open these files. > > Thank you, > Natalie Walsh

ChimeraX Questions
by Bani Kaur 01 Jul '23

01 Jul '23

Hi, I hope you are doing well! My name is Bani Kaur and I am an active user of ChimeraX for a research project concerning protein modeling, specifically with the CFTR protein. I have been running into issues with showing atoms on my residue, specifically after I change the romater. I am not sure what to do about this as I have downloaded the latest version of ChimeraX. I have attached a photo where the left one is the selected residue (Thr) and the right photo is the residue when it is changed to Ile. [image: Screen Shot 2023-06-30 at 5.38.22 PM.png] Additionally, I am not able to see clashes for some very reason and am only able to see it when limit by selection is unchecked, but for my research project, we require that it is checked in the clashes settings. I have attached a photo of the settings. [image: Screen Shot 2023-06-30 at 5.39.01 PM.png] Thank you so much for your help! Best, Bani Kaur
