[gmx-users] Can not read/write topologies to file type trr

[Martin Höfling]

Hi all, 

a short simulated-annealing simulation crashes with:

Program mdrun, VERSION 3.3.2
Source code file: gmxfio.c, line: 784

Fatal error:
Can not read/write topologies to file type trr

I read the a bit the sourcecode of and it seems as if it does sth like 
determining and setting the do_read/write functions for file I/O.

Any idea where this could come from?

Best
