This will restrain all atoms in residues 1 to 384. The sander or pmemd
programs don't have any notion of what "kinds" of atoms these are (e.g.
protein, lipid, solvent, head-groups, tails, etc.) Make a pdb file using
ambpdb, and look to see what atoms are in the residues you have chosen.
Don't be afraid to experiment: run a short simulation and see what moves.
