NAME

gmx-saxs-legacy - Compute small angle X-ray scattering spectra

SYNOPSIS

gmx saxs-legacy [ -f [<.xtc/.trr/...>] ] [ -s [<.tpr/.gro/...>] ]
[ -n [<.ndx>] ] [ -d [<.dat>] ] [ -sq [<.xvg>] ] [ -b <time> ]
[ -e <time> ] [ -dt <time> ] [ -xvg <enum> ] [ -ng <int> ]
[ -startq <real> ] [ -endq <real> ] [ -energy <real> ]

DESCRIPTION

gmx saxs-legacy calculates SAXS structure factors for given index groups based on Cromer's method. Both topology and trajectory files are required.

Structure+mass(db): tpr gro g96 pdb brk ent

-n [<.ndx>] (index.ndx) (Optional)

Index file

-d [<.dat>] (sfactor.dat) (Optional)

Generic data file

Options to specify output files:

-xvg <enum> (xmgrace)

xvg plot formatting: xmgrace, xmgr, none

-ng <int> (1)
