and also the same .xtc (or .trr) file?

no, g_covar stores the average (and reference) used during the covariance analysis in the
eigenvec.trr file, so this should automatically be correct.

If you can't find the mistake, please specify step by step what you've done.
(or send me (ie not the list) a minimal set of files with which the problem can be reproduced).
