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))

BaseApplicationSANS.viewLogSANS()[source]

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

I(q)

BaseApplicationSANS.viewSANS()[source]

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