[gmx-users] Trajectory

[Alex]

Dear Gromacs user,

I have a single 200 ns simulations's xtc-trajectory for which the
"compressed-x-grps        = non-Water" option has been used for the first
100 ns of it, so that it contains no water molecule, while the second 100
ns part of it contains water. The mdp file was change at 100 ns by removing
the "compressed-x-grps        = non-Water".

Now when I apply the gmx trjconv on this .xtc file the outputs are just
from 0 to 100 ns irrespective of the .tpr file I use, I mean the 100 ns is
last frame are read, but I need to extract data from after 100 to 200 ns
too.

So, I wonder if there is any way to save me from re-simulating?

I already have the .trr file which contains all the atoms during the whole
simulation but it has collected the data in a very low frequency respect to
the xtc.

Regards,
Alex
