NAME¶

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

SYNOPSIS¶

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

DESCRIPTION¶

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