What does gmxcheck tell you about these .trr files?

Also, it is better to give exact command lines with copy-pasted screen output, instead of leaving us to guess at what you're trying.

Dear colleagues,

I successfully finished a 3 ns gromacs run using 40 nodes. When, I tried to convert .trr file to .xtc using trjconv, the run stops at 560 frame giving error "cannot determimine precision of trn file". I tried various options like -skip, -b and -e, -dt option as well as -ndx option . But, each time, the run stops at 560. The second run I gave for 6 ns and this time, the trjconv stops at 1180 frame. I have observed the .trr files occupying huge memory space - 18 G for 3ns and 34 G for 6 ns runs respectively. Memory is not a problem, as I have lot of disk space available. My system is a pentamer with 1052 residues and 47201 water molecules.The simulation ran for 5 days.

I would be extremely thankful for any kind of suggestions in this regard.
