Hello Accelrys Community,

I started a 1 nanosecond molecular dynamic simulation and then I had to stop the run early after only completing less than half of the simulation time (444 ps). I then restarted the run and finished the remaining simulation time in a second simulation. Now I have two trajectories for the 1 nanosecond simulation that I wish to merge together. When I click on the process trajectory file and load the two trajectories into the window that pops up, I notice that the trajectory file (dcd) for the stopped simulation has 1000ps as its stop time and not 444 ps. When I try to merge the two trajectories together this creates an error message and discovery studio does not merge the trajectories. This problem happens every time I stop a run short of the initial simulation time required. Has anybody figured out a way to work around this problem (perhaps by editing the first dcd file?)?

Thank you for your help,

David
