[Chimera-users] About direct fetc hing biological assemblies into Chimera

Mon Jun 16 09:27:14 PDT 2014

Hi Tom,

Thanks again for this. I found that when I specify a PDB using uppercase
letters via a script, the command doesn't work. But lowercase letters do
work. I catch it in my script, but you may want to build this into the
command for other users, kind of like how regular PDB fetch does it.

Thanks!
Darrell
