Re: restart simulation writing in the same .dcd file.

If you are going to analyze trajectories using VMD, it does not matter how many dcd file you have. You can simply load all the dcd files alternatively in VMD.

Subject: namd-l: restart simulation writing in the same .dcd file.

Dear NAMD users, the energy was out for some time, so the simulation i was performing on the cluster stopped. Now i want to restart using the restart files, but i need NAMD to keep writing at the same dcd file, it can't overwrite the old one, because the analysis i'm going to do require only one dcd file, i can't have multiples.
So is there some tag on NAMD to tell it to keep saving the coordinates on the same dcd file? Or if there isn't really a way of doing that, if someone knows how to merge two dcd files.

Thanks everyone!
