McXtrace: SAXSNanodiscsFast

[ Identification | Description | Input parameters | Output parameters | Links ]

The SAXSNanodiscsFast Component

A sample of monodisperse phospholipid bilayer nanodiscs in solution (water).

Identification

  • Site:
  • Author: Martin Cramer Pedersen (mcpe@nbi.dk)
  • Origin: KU-Science
  • Date: May 2, 2012

Description

A component very similar to EmptyNanodiscs.comp - however, the scattering
profile is only computed once, and linear interpolation is the used to
simulate the instrument.
