Dear Justin

Thanks for your reply.

My system contains dopc lipid. ns.xtc and ns.tpr files contain all atoms
related to dopc molecule.

I want to obtain number of atoms in a first group (C38 atom in dopc) which
are located in special distance (0.74 nm) of the second group (rest of
atoms in dopc).

I put 2 groups in the ns.ndx file: 1) C38 atoms and 2) rest of atoms.

Best regards
