Hello,

Is there an easy way to generate a new Gromacs trajectory file md_subset.xtc from an existing trajectory file md_allatoms.xtc where I remove everything (including solvent) except a subset of my protein residues?

I believe the Gromacs command "gmx trjconv" has the ability to select subsets of atoms, but I have not been able to figure out how to use it to this end.

Thank you very much for your help!
