> Hi all,
> Is there documentation that specifies which columns in a pdb file are interpreted as the 'segname' field by vmd? It seems to be columns 73-75 in the pdb files that IEUR(tm)ve seen, but I wanted to make sure that's correct.

>From what I can see the segid field used to be part of the PDB standard
but was removed a long time ago. The 1996 revision mentions it:

In later versions that field is dropped.
