Hi Priya,
If your mdcrd file is larger than 2GB it is very likely that VMD won't read
it. You can use ptraj to split it up into chunks or alternatively build a
smaller file with say only every 100th step in it.
Also VMD cannot deal with pathnames longer than a certain number of
characters - I don;t know the exact number, probably 128 or 256. Either way
it manifests itself as an "unable to open" message so you may want to check
the length of your path and try moving it to a shorter directory tree.
Good luck
Ross
