The `SANSPDB` Component

A sample describing a thin solution of proteins. This components must be compiled with the -lgsl and -lgslcblas flags (and possibly linked to the appropriate libraries).

Description

This components expands the formfactor amplitude of the protein on spherical
harmonics and computes the scattering profile using these. The expansion is
done on amino-acid level and does not take hydration layer into account.
The component must have a valid .pdb-file as an argument.

Input parameters

Parameters in boldface are required; the others are optional.
