Gromacs users,
I want to look at the temperature difference between groups, to check whether 
temperature coupling is working ok (specifically if the lipid is at the same 
temperature as the water).
Unfortunately, I've rather foolishly deleted all my trrs due to a lack of 
space, thinking xtc/edr would be all I needed.  While I can get the *system* 
temperature from g_energy, it doesn't take an index file, and g_traj needs 
velocities (which I don't have any more).  Anyone know of a way around this, 
short of continuing the simulations and taking the .trr from that?

Alan.

If g_energy does only give you the system T it means you have not used T-coupling groups and hence your Temperatures will differ between lipid and water. Best way to know is to continue the simulation for few hundred ps and don't delete the trr :(.
