Thank you Justin. Is it possible to choose protein and ligand separately (e.g. 
1|13) in the trjconv, since I chose protein-ligand subgroup which was taken as 
a whole and ligand can not be distinguished individually ? Or should I do any 
modifications in VMD ?

Use trjconv to save whatever subset of coordinates you want.
