The message below seems to relate to REMD inside pmemd. Any comments from
those involved with this? (Seems to relate to sander6 or pmemd 2.01(?)
formats.) I'm confused by the subject line, since I don't think(?)
there is support for REMD in pmemd.amoeba.
...thx...dac

Robert Best suggests there is a bug in the (regular and AMOEBA) pmemd
inpcrd_dat.F90 which causes the temperature not to be read from the
restart file. It is the line 141 in the attached file. The addition of
"local_temp0" should fix this problem.

In the amber development version it is just line 141 in inpcrd_dat.F90. I've attached the corrected file.
I assume everyone uses binary or netcdf restarts now so that's why it wasn't picked up?
