[gmx-users] Heat capacity of the system

[Mark Abraham]

Hi,

Rerun should not be doing anything with the velocities, because a
trajectory file does not have all the necessary state to reproduce what the
original mdrun did. (I forget whether we've actually stopped mdrun -rerun
from pretending to, but that's at least the plan.) Calculate your heat
capacities from the data in the original .edr files.
