Hi Elaine, It would be nice to have representation settings like "cartoon style" or "sticks" accessible on a per-chain or per-residue basis. This is a feature I use a lot in pymol and VMD. Best wishes James Elaine Meng via ChimeraX-users <chimerax-users@cgl.ucsf.edu> escribió:
Hi Mauricio, I don't understand "the ability to superimpose the view of one chain" -- can you explain it in more words? What is it that you want, that cannot be done currently? Maybe it is already possible but I didn't explain it because I didn't realize that was what you wanted.
If you mean to make "cartoon style" work on just a chain instead of whole model, it may be unlikely since the settings it controls are per-model (not per-chain or per-residue). However, it is already easy to split chains into separate models with "split."
Sorry if I am misunderstanding what you meant, however. Elaine ----- Elaine C. Meng, Ph.D. UCSF Chimera(X) team Department of Pharmaceutical Chemistry University of California, San Francisco

Hi Elaine,
Thank you very much for your prompt reply. Your workarounds were very helpful, I was able to tweak thickness and transparency, and arrived at a satisfactory display composition. Would you consider as a request feature the ability to superimpose the view of one chain?
Thank you! Mau

I can't tell from your question whether they are in two separate models or not. Even if they're together in one PDB file they can be defined as separate models (as is done for NMR ensembles, e.g. PDB 1kfp). If the purple one is model #1 and the gray one is #2, could be something like:
cartoon style #1 width 1 thick 1 xsect round transparency #2 50 targ r
...of course, you could use different width/thickness and transparency values.

The cartoon style command works on whole models, so you would need them to be in separate models for that approach. If your current PDB file does not have them in separate models, you could either text-edit it to add MODEL and ENDMDL records, or (probably easier) use the "split" command after opening it. <https://urldefense.com/v3/__https://rbvi.ucsf.edu/chimerax/docs/user/command...

Hi,
I am new to ChimeraX, thank you for making this great software available.
I loaded a pdb file that has 2 amino acid chains aligned (chimerax.png). These chains are a model (gray) and template (purple).
As you can see, the two chains look weaved or blended. I would much prefer to display the uninterrupted template around to model, to visually represent their fit. Is there a way to do this?
I am attaching a second image (ideal_display.png, generated elsewhere) with the visual outcome I am after (the purple chain is the template, the rainbow-colored chain is the model).
Thank you Mauricio Losilla, PhD Integrative Biology; and Ecology, Evolution, & Behavior Michigan State University he, him, his <ideal_display.png><chimerax.png>
