[chimerax-users] downloading pdb files from another webserver

[Eric Pettersen]

Hi Amith,
	If you still want to do your script thing despite the res_numbering attribute trick, you would use the "runscript" command (https://www.rbvi.ucsf.edu/chimerax/docs/user/commands/runscript.html <https://www.rbvi.ucsf.edu/chimerax/docs/user/commands/runscript.html>) rather than "open".  "Open" has no ability to pass non-keyword arguments to the function opening the file.  The arguments you give to runscript will be available in the script via sys.argv.
