CCL: MD Simulation by gromacs

Hi Maria,
 You need to first confirm the protonation state of HIS residues for your
 system. Then look at the residues in the rtp file and rename the HIS
 residues (in you pdb/gro) file and then run the pdb2gmx command.
 It is better you send the gromacs related messages to the gromacs mailing
 list. You might end up help from others also.
