When running a simulation protocol such as the Standard Dynamics Cascade for a large molecular system, a long dynamics simulation would require a large amount of memory to add all the trajectory frames into the output molecule file. If the server does not have enough memory, then the .dsv file in the run Output folder may not be updated with the trajectory frames from the CHARMm dcd file.

When this happens, there should still be the .dcd file and the .ene file in the Output folder. You can open the _noconfs.dsv file in DS, then use the Structure > Animation > Load command to load the .dcd file into the active molecule window to create the conformations, and proceed with analysis as usual.
