Re: Would it be possible to continue a simulation from any snapshot of a trajectory?

Hi,

The coordinates and box information are stored in the dcd file, so
creating restarts for that should not be a problem. However, the
velocities cannot be recovered from the trajectory itself. So unless you
specifically saved a velocity trajectory you won't have the vel file and
therefore will need to re-assign velocities from scratch. Depending on
what you want from the trajectory, that might not be an appropriate restart.
