Program gmxcheck, VERSION 4.0.7
Source code file: trnio.c, line: 66

File input/output error:
Can not determine precision of trn file
-------------------------------------------------------

This means that my FIle5.trr stopped at time 58.0000 (the correct would be 2000.0000)? IS THere any way to fix it?

Thanks !

Not likely. If a frame is corrupt, tools like trjconv that can parse them out generally fail as well. You can, however, use trjconv -e 58 to save the first frames of "File5.trr" and then continue on from a checkpoint to re-collect the remaining data.
