I am doing a membrane protein simulation and has generated a system
following most instructions from NAMD's tutorial.
I already have the pdb coordinates and psf file built with
top_all27_prot_lipid.inp. If i wanted to use CHARMM36 for my lipid
parameter, is it correct to generate a new psf file with psfgen specifying
top_all36_lipid.rtf for my lipids and top_all27_prot_lipid.inp for the
rest of the system using my already available coordinates?
