SANS: General description

Purpose

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. In unit-aware applications, a file parameter value may also include an explicit unit, for example Mw=1131 Da;T=25 ºC;gdot=0.1 1/s;.

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

• In unit-aware applications, column headers may include units in square brackets or parentheses, for example t [min] or G' [kPa]. See Units for the supported units and current limitations.

.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
...               ...
