[gmx-users] Converting a tpr file to an older version of gromacs

[Paul bauer]

Hello,

there is no real supported way of doing this. You would need to 
re-create the TPR in the version you want to use it in.
Can you use an external tool instead of g_mmpbsa that supports reading 
the newer file format?

Cheers

Paul
