GROMACS version: Gromacs 2020.2
GROMACS modification: No
I found a strange thing while working with Gromacs 2020. I have a .tpr file containing the two protein chain A and B. When I was trying to make an index of chain A and chain B using the gromacs 2020 make_ndx program, it shows 0 atoms.
Whereas, when I use the gromacs 2018.1 make_ndx program for the same task, it works and created an index group of protein chain A and chain B.
Please find attached screenshots, one for gromacs 2018 and other while using gromacs 2020. I don’t know whether user forum is a right platform to report this or I need to report this somewhere else. Thank you very much.
