That should work just fine. Try something like this:

mol new {your_psf_file.psf} type {psf} first 0 last -1 step 1 waitfor 1
mol add file {your_dcd_file.dcd} type {dcd} first 5000 last -1 step 1 waitfor -1 top

But I write same commands in a script.tcl and script is sourced in command prompt, it gives an error "invalid command name "last"". I will appreciate any suggestion to over come this problem.
