Re: loading of large dcd files

This question is best suited for the VMD list, but in general there
shouldn't be any problem loading that many frames into VMD, provided
that you have enough memory and the input files aren't corrupted.
Again I would direct your question to the VMD list. But as a test to
prove to yourself whether it is a VMD or input file problem, you
could create a similarly large dcd file by using catdcd to string
together your initial pdb file 10000x and then try to load that.

Good luck.
