McStas: SANSPDB

[ Identification | Description | Input parameters | Links ]

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).

Identification

  • Site:
  • Author: Martin Cramer Pedersen (mcpe@nbi.dk) and Søren Kynde (kynde@nbi.dk)
  • Origin: KU-Science
  • Date: October 17, 2012

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.
