The .tpr and the .trr files will correspond per definition, provided
the former is used to generate the latter. This is not the case for
the .xtc. My guess is you do have a mismatch. Did you specify
xtc-grps? In that case you might want to extract a corresponding
reference structure from your .tpr.

Hope it helps,
