thanks for your answer.
well, I am not working in parallel and I don't have virtual sites, so I
was already excluding non-matching problems related to these cases. What
else could it be and how do I check if files are matching or not?
I tried with gmxdump -s topol.tpr and indeed the first atom in topol.tpr
is a N and has number 0, but I thought this is always the case.
btw I have just tried gmxcheck -f traj.trr -s1 topol.tpr on the tutorial
files... also there I get this long list ... what am I doing wrong?
