Austin,
Have you tried to look into the rotamer distribution you are after
without T-WHAM ? I recommend you do that first, do not add a layer of
complication just yet at your level.
So, try to figure out which temperature is the one you want, and look at
that mdcrd as if it was a regular md run (but do not think of it at
time-ordered because it is not).
