The easiest is to feed the last PDB file you've outputted to the
peptideB command (using the -pdb flag to load that file). From what I
remember, the same should hold from REMD, though all replicas will
load that particular file (I haven't implemented a routine to load
different PDB files for different replicas).
Let me know if that's still unclear.
