g_protonate(1)					 GROMACS suite, VERSION 4.5.4-dev-20110404-bc5695c				    g_protonate(1)

NAME

       g_protonate - protonates structures

       VERSION 4.5.4-dev-20110404-bc5695c

SYNOPSIS

       g_protonate -s topol.tpr -f traj.xtc -n index.ndx -o protonated.xtc -[no]h -[no]version -nice int -b time -e time -dt time

DESCRIPTION

	g_protonate reads (a) conformation(s) and adds all missing hydrogens as defined in  gmx2.ff/aminoacids.hdb. If only  -s is specified, this
       conformation will be protonated, if also  -f is specified, the conformation(s) will be read from this file, which can be  either  a  single
       conformation or a trajectory.

       If  a   .pdb  file  is supplied, residue names might not correspond to to the GROMACS naming conventions, in which case these residues will
       probably not be properly protonated.

       If an index file is specified, please note that the atom numbers should correspond to the  protonated state.
