Right, thank you very much Tom !
Indeed, the idea was to control precisely each rotation center for each model.
So presently even an approximate method that would allow to apply such rotation for any number models described in your message "roll models #1-6 center independent" still has not been integrated, right ?
Hi Enrico,
Allowing the roll command to roll each model about its own center of rotation has been discussed a year ago
https://mail.cgl.ucsf.edu/mailman/archives/list/chimerax-users@cgl.ucsf.edu/thread/LA3BR36XCQ7XQYFOTWJJZVKE3YIQ67TS/#LA3BR36XCQ7XQYFOTWJJZVKE3YIQ67TS
and there is a ChimeraX feature request for it
but currently there is no such option. I'm not quite sure what such an option would look like. In your example you use "center #1 & protein". In the prior discussion I think the idea was something like "roll models #1-6 center independent" and this would be the same as using "center #1", not "center #1 & protein". But you raise an interesting case where you want to have finer control over the rotation center. For instance, what if I had several homolog structures and I wanted to rotate each about a specific residue or active site ligand, e.g "center #1:215".

Dear ChimeraX users!
Using til command I split six superimposed structures, displaying them as the 2x3 table and then rotate each object along its axis within each grid using "roll" in the following way:
# for 6 different object
roll models #1 center #1 & protein
roll models #2 center #2 & protein
roll models #3 center #3 & protein
roll models #4 center #4 & protein
roll models #5 center #5 & protein
roll models #6 center #6 & protein
Would it be possible to simplify this to one "roll" command that will automatically rotate all displayed objects in the separate grids along its axis ?
Many thanks in advance
Enrico
