You can't do this (directly): trajectory files have lots of coordinates
(frames) in them, whereas a restart file has only one set of
coordinates. pmemd doesn't know how to start from a trajectory file.
Do you have a "final" restart file (created with the "-r" flag)? Might
that not be what you want here, as a starting point for the next MD
segment?
If not, do this: use cpptraj, with trajin being the trajectory file:
choose the frame you wish to use. Set trajout to write a restart file.
Then you can use the restart file you just created. It won't have any
velocities, so you will have to set ntx=1 and tempi to the initial
temperature you want.
....hope this helps....dac
