Dear Shay, dear Justin, dear Gromacians My problem is solved. I used following command
$ g_mindist -f system_onlyCa.xtc -s system_onlyCa.pdb -n system_onlyCa.ndx -o atm-pair.out The PDB file "system_onlyCa.pdb" had a header which seems to have confused the counting of the "g_mindist" command. After deleting the the PDB header/ comments, I get the correct results.
