Well, I don't know what you call it when the file causes the program to crash other than "too large to read"-over loads memory maybe?

The resultant dcd file is too large to read into VMD (the program crashes after reading in about 250 frames or so). Is there any workaround for me to get the last structure so I can start my simulation again? All I have is the starting geometry, the psf and the dcd file (no other restart files). Surely there is something I can read this file into.

i don't get the "too large to read" part. if all you care about is the
last few frames, just tell VMD to skip over the first 300 or so by
changing the entry of the first frame to load in the file load dialog.
