Re: help running NAMD energy at multiple stable temperatures (newbie)

Hi Marie,
potential energies are independent of temperature, and since those are
what namdenergy measures, you will not see different results when
analyzing a trajectory. You would need to actually run your simulation
at different temperatures to see any effect.
Hope this helps.
