Thanks for the suggestion.
I just tried and the problem presists.
Just to be clear, the right way is to use the g_covar.trr file, correct?

  -f       traj.trr  Input        Full precision trajectory: trr trj cpt

Here the full precision means double precision? I see you use single
precision.

I have never tried this one, perhaps someone else may give you some
suggestions.


Full precision and double precision are different, though not completely unrelated in a sense. You can have a single- or double-precision .trr file that is still full precision, all it means is that a different number of decimal points are saved. A .trr has greater precision than an .xtc (independent of a single- or double-precision calculation) simply because it stores more decimal places.
