[gmx-users] Selection syntax in make.ndx

[James Starlight]

Hi all!

I am in charge with the analysis of multi-chain protein where each
chain defined as separate itp file in the topology.
My task is to make new ndx file for given tpr file defining chain A as
separate ndx group and all of the rest of the protein group but not
Chain A. Assuming to select chain A I just put Chain A (or
alternatively resid 1-100 for my case) how I can define selection
Protein and not Chain A or Pprotein and not resid 1-100 excluding
chain A or first 100 residues from the second selection?


Thanks for help!

James
