[gmx-users] strange error

[jaimin at iitb.ac.in]

Dear Users:

I made only the following two changes in the pr.mdp file in the folder
"speptide" that comes alongwith the package:

nsteps              =  500000	; total 1000 ps.
nstxout             =  5000

On running gmxcheck -f pr.trr:

Checking file pr.trr

Now, the input files from the "speptide" folder are copy-pasted into
the new folder. I make exactly the same changes to the pr.mdp file in my
protein's folder. After MDrun, when I do gmxcheck:

Checking file pr.trr

Among the things that this error leads to is, it disallows me to see the
trajectory.

Can someone please point out what is happening?
