Hello all,

I am doing the simulation of a pentapeptide for one nano second. 
In between there is a power failure and the simulation stopped in 
the middle and when I try to resume it using tpb conv I got the 
following error.

READING COORDS, VELS AND BOX FROM TRAJECTORY after_md.trr...

trn version: GMX_trn_file
Read frame    962: step 240000 time  480.000Fatal error: Can not 
determine precision of trn file, quit!

The command I used was:
tpbconv -s after_md.tpr -f after_md.trr -o extend.tpr -extend 
1000

But I did one thing. I used the following command:
tpbconv -s after_md.tpr -f after_md.trr -o extend.tpr -time 480

It did work fine. But, the problem is the earlier trr file had 
steps upto 240730 (remember 240000 steps corresponds to 480 ps). 
Now when I try to concatenate these two files with trjcat, will 
the additional 730 steps (whose precision could not be determined) 
that were done in the first step be taken care of. Or is there any 
other method to continue the file if the
last coordinates are not written.

Regards
Prakash sista
