SYNOPSIS

gmx protonate [-s [<.tpr/.tpb/...>]] [-f [<.xtc/.trr/...>]]
[-n [<.ndx>]] [-o [<.xtc/.trr/...>]] [-nice <int>]
[-b <time>] [-e <time>] [-dt <time>]

DESCRIPTION

gmx protonate reads (a) conformation(s) and adds all missing hydrogens as defined in oplsaa.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.

OPTIONS

Options to specify input and output files:

-s [<.tpr/.tpb/...>] (topol.tpr) (Input)
Structure+mass(db): tpr tpb tpa gro g96 pdb brk ent

-f [<.xtc/.trr/...>] (traj.xtc) (Input, Optional)
Trajectory: xtc trr cpt trj gro g96 pdb tng

-n [<.ndx>] (index.ndx) (Input, Optional)
Index file

-o [<.xtc/.trr/...>] (protonated.xtc) (Output)
Trajectory: xtc trr trj gro g96 pdb tng

Other options:

-nice <int> (0)
Set the nicelevel

-b <time> (0)
First frame (ps) to read from trajectory

-e <time> (0)
Last frame (ps) to read from trajectory

-dt <time> (0)
Only use frame when t MOD dt = first time (ps)

KNOWN ISSUES

- For the moment, only .pdb files are accepted to the -s flag
