[gmx-users] Analysis of trajectory form Gromacs 5.1.2. in Gromacs 5.0.4

[König, Melanie]

Thank you Justin for your quick reply. 

Like you suggested, I built a new .tpr file with 5.0.4 and everything worked fine.

You just need to build a new .tpr with 5.0.4; trajectory format has not changed.

In general, do not expect to analyze new files with old software.  GROMACS is
backwards-compatible, but not forward-compatible.
