[gmx-users] About a restart problem

[kyungchan chae]

Hello,

I have a problem in using checkpoint file (Gromacs 4) to restart my 
simulation
When I restart my parallel simulation by using 'append' option
 : mdrun -cpi state.cpt  -append yes  -cpt  30 

the following error messages showed up:

   "Program mdrun, VERSION 4.0.99_development_20090120
     Source code file: checkpoint.c, line: 1238

     Fatal error:
     Truncation of file traj.trr failed. "

Could you give me any advice about this problem?
