       gmx-trajectory - Print coordinates, velocities, and/or forces for selections

SYNOPSIS

          gmx trajectory [-f [<.xtc/.trr/...>]] [-s [<.tpr/.gro/...>]]
                       [-n [<.ndx>]] [-ox [<.xvg>]] [-ov [<.xvg>]]
                       [-of [<.xvg>]] [-b <time>] [-e <time>] [-dt <time>]
                       [-tu <enum>] [-fgroup <selection>] [-xvg <enum>]
                       [-[no]rmpbc] [-[no]pbc] [-sf <file>] [-selrpos <enum>]
                       [-seltype <enum>] [-select <selection>] [-[no]x]
                       [-[no]y] [-[no]z] [-[no]len]

DESCRIPTION

       gmx  trajectory  plots  coordinates, velocities, and/or forces for provided selections. By
       default, the X, Y, and Z components for the requested vectors are plotted, but  specifying
       one or more of -len, -x, -y, and -z overrides this.

       For  dynamic  selections,  currently the values are written out for all positions that the
       selection could select.

       Options to specify output files:

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

       -tu <enum> (ps)

       -xvg <enum> (xmgrace)
              Plot formatting: none, xmgrace, xmgr

       -[no]rmpbc (yes)
              Make molecules whole for each frame

       -[no]pbc (yes)
              Use periodic boundary conditions for distance calculation

       -sf <file>
              Provide selections from files

       -selrpos <enum> (atom)
              Selection  reference  positions:  atom,   res_com,   res_cog,   mol_com,   mol_cog,
