2017-12-05 Thread ZHANG Cheng
Dear Gromacs,I am doing the RMSD calculation for a particular group of protein residues. My system also has water molecules so there are more than 9 atoms. Thus, the 10th atom is indexed as 0, and 11th atom as 1, and so on. So if the index file for my group has an entry of 1, how c
