[gmx-users] How to generate proper index files...

[curtchr1 at iit.edu]

Hello all,

I am currently trying to generate an index file for a two component protein,
two component as in I have two separate ITP files for the dimers that compose
the protein.  When I generate the index file from the .gro file, which does
not have any syntax to differentiate between the dimers of the protein,
I get, as expected, an index file for PROTEIN, not for two separate units.
 How might I overcome this?  

Thanks for the help.
