SASA per residue

GROMACS version: version 2020.1-Ubuntu-2020.1-1
GROMACS modification: No

Hello,

I have a protein and I would like to calculate the SASA of the specific residues of my protein. In other words, I would like to perform SASA per residue for a specific part of the protein. Is it possible to do that using gmx_sasa command? How can I do this?

I really appreciated all your help!
