Dear VMD users,

I am trying to extract frames from trajecory using command line - I want to
run it as a job as I have to save 250 frames every 5000 having over 300
0000 frames.

I wish to srite a script which will load my pdb, load given frames of
interests and save it as a trr.xtc file.

I started:

mol new Protein.pdb
mol addfile MD.xtc type xtc first 0 last 250 waitfor all

Can you please suggest a command to save it now?
