[Chimera-users] working with PDB files from XplorNIH

[Miriam Gochin]

I am wondering if it is possible in Chimera to select between different chains in a multimer that are defined by the SEGID parameter in XPLOR.  This appears on columns 77-80 of the PDB file, 
e.g. in this homotrimer:

ATOM        1  N   GLN     1       -2.276 -27.488  29.307  1.00  0.00         A
...
ATOM     684  N   GLY     1        4.365 -26.465  20.200  1.00  0.00         C
---
ATOM   1357  N   GLN     1      13.798 -26.207  29.441  1.00  0.00         E
...

Atom selection results in picking up 3 atoms instead of 1, since Chimera expects the chain designation after the residue name.  The XPLOR output is therefore not compatible with Chimera input requirements and I am wondering if there is a workaround.

Many thanks for any suggestions.
