fairmd.lipids.analib.formfactor module

Analysis module for FormFactor curve.

fairmd.lipids.analib.formfactor.get_mins_from_ffdata(ffdata: ndarray) → list[float][source]

Find the positions of minimums in form factor data.

fairmd.lipids.analib.formfactor.calc_ff_scaling_distance(ffd_exp: ndarray, ffd_sim: ndarray) → tuple[float, float][source]

Calculate scaling factor and Chi2-distance for exp SAXS values.
