Hi Alex, That's "Unix order", i.e. the same order that the 'ls' command returns them. ChimeraX is using Python's "glob" module to expand "*.pdb" into a list of file names. Therefore you could use a different "glob" to get the order you want, namely "open ?.pdb ??.pdb ???.pdb" (with folder names prepended if necessary. --Eric Eric Pettersen UCSF Computer Graphics Lab

I have a series of pdb's in a folder numbered 1 - 500 (so 1.pdb ... 500.pdb). I'm opening them in ChimeraX using *.pdb.

I'm expecting 1.pdb to have ID1 and 2.pdb to to be ID2, but it appears ChimeraX is only looking at the first digit and not the whole number. Is there a way around this? For now, my work around is to use 001, 002 ... 500 instead <image.png>
