Dear gromacs users,

   I was trying to dump structures from MD.trr using trjconv. The MD.trr
has 0ns to 382ns of data. (i checked the MD.log file also).  However, when
i try to dump structures beyond 25ns, with the following command :
*gmx trjconv mpi -f MD.trr -dump 27000.000 -dt 1000 -s MD.tpr -b 20000.000*

*it gives the following error :WARNING no output, last frame read at

I have also tried to check with gmxcheck but it only runs till 20ns.

trjconv and or gmxcheck did not give any error with MD.xtc which was
generated during the simulation.

I require the MD.trr as i  need velocity and force information for my

Kindly suggest something!!
Kind Regards,
