SANS: General description

Purpose

Application to Analyze Data from SANS experiments

Data Files

• The first line of the file should contain the sample parameters separated by semi-colons (;). It may contain any number of parameters which will be read and saved as file-parameter in RepTate.

• Then the data columns should appear, separated by spaces or tabs.

.sans extension

Text files with .sans extension should be organised as follows:

• .sans files should contaion at least the parameter values for the:

  1. Sample molecular weight Mw,

  2. Volume fraction of deuterated chains Phi.

• 2 columns separated by spaces or tabs containing respectively:

  1. scattering vector, \(q\),

  2. scattered intensity, \(I(q)\),

A correct .sans file looks like:

Mw=407;Phi=0.964;
0.0098083         24.9121
0.010647          22.9176
0.011486          21.7702
0.012325          20.0757
0.013164          18.6836
...               ...

Views

log(I(q))

ApplicationSANS.viewLogSANS()

Logarithm of the scattered intensity \(\log (I(q))\) vs the logarithm of the scattering vector \(\log(q)\)

I(q)

ApplicationSANS.viewSANS()

Scattered intensity \(I(q)\) vs scattering vector \(q\) (both axes in logarithmic scale)

Zimm

ApplicationSANS.viewZimm()

Zimm plot: \(I(q)^{-1}\) vs \(q^2\)

Kratky

ApplicationSANS.viewKratky()

Kratky plot: \(q^2\cdot I(q)\) vs \(q\)
