Hi eric thank you so much for your answer. I think it is important because for those guys playing with CHARMM/NAMD/XPLOR pdb file that shifting from PyMol (Where segid specification exists in the sele command) to ChimeraX (my case), it will really be a nice option. Also because chainid does not exists in these pdb format. Thank you again. Best regards.

I will open an enhancement-request ticket in our bug-tracking database for it, with you cc'ed so that you will know when progress occurs. It may take awhile to get to given our other development priorities. --Eric Eric Pettersen UCSF Computer Graphics Lab On Oct 26, 2022, at 2:37 AM, CUNIASSE Philippe via ChimeraX-users <chimerax-users@cgl.ucsf.edu<mailto:chimerax-users@cgl.ucsf.edu>> wrote: Dear all, Is there a way in ChimeraX to make a selection by segid (column 73-76 in pdb format from CHARMM of XPLOR)?
