Hi,
Your xtc file has only the group you wrote, so it isn't valid to index into
it with an index file that was made for a conformation with many other
atoms. That's the mismatch the message mentions. For your xtc, "System" is
the subset of *it* that you seem to want for your analysis. Note that
Hello, I'm using GROMACS 5.1.13 and ran into a problem I've never
encountered before. I've run a simulation on a zinc-finger DNA complex and
defined a group in my index filed called "Protein_DNA" from the default
"Protein" and "DNA" groups. This group should contain 4666 atoms, which it
does.
