Rima,
You can either use the "first", "last", and "stride" controls in the
molecule file browser window, or use the same options with the mol new/addfile
text commands. If you want to see the whole trajectory, I'd recommend just
setting the "stride" value in the GUI to something like 10, as that will
cut your memory use down to 300MB rather than 3GB. I hope to make changes
in future versions of VMD which will warn the user to help prevent them from
loading trajectories that are too large to fit in available memory.
In the mean time, just set the stride/step size (GUI / text command) and
see if that does what you need.

The huge DCD file cannot be uploaded in VMD, it reaches its memory limit and crashes. Is there a way I can break the DCD file into sub-parts and then upload it? or if there is any way around this problem?? Any help would be much appreciated.
