[chimerax-users] Non contiguous residues selection from command line

[LEONARDO SORCI]

Thank you, Elaine, 
It works now, and I noticed that the issue was in the syntax as I did not include a space after "select". As per your example:
select  :172,192-198,208,214 (OK)
select: 172,192-198,208,214 (error in ChimeraX, unknown command)

Standard Chimera looks more permissive in this regard, as both options work.

Hi Leonardo,
Selecting a bunch of residue using their numbers is basically the same as in Chimera, e.g. in ChimeraX you could use command:

select  :172,192-198,208,214

Command-line specification in ChimeraX:

Differences in command-line specification vs. Chimera:

I hope this helps,
Elaine

In standard chimera, I would use the command SELECT with numbers, commas, and hyphens (e.g., SELECT: 172,192,193,208:214).
