Test Data

Test data sets are included as a convenience to our users. Look in the test sub-folder in your SasView installation folder.

The data sets are organized based on their data structure; 1D data, 2D data, SASVIEW saved states, and data in formats that are not yet implemented but which are in the works for future versions.

1D data sets have at least two columns of data with Intensity (assumed absolute units) on the Y-axis and Q on the X-axis.

2D data sets are data sets that give the deduced intensity for each detector pixel. Depending on the file extension, uncertainty and meta data may also be available.

Saved states are projects and analyses saved by the SasView program. A single analysis file contains the data and parameters for a single fit (.fit), p(r) inversion (.pr), or invariant calculation (.inv). A project file (.svs) contains the results for every active analysis.

Some of the available test data is described below.

1D Test Data

AOT_Microemulsion
  • Aerosol-OT surfactant stabilised oil-in-water microemulsion data at three contrasts: core (oil core), drop (oil core + surfactant layer), and shell (surfactant layer).
  • Suitable for testing simultaneous fitting.
hSDS_D2O
  • h25-sodium dodecyl sulphate solutions at two concentrations: 0.5wt% (just above the cmc), 2wt% (well above the cmc), and 2wt% but with 0.2mM NaCl electrolyte.
  • Suitable for testing charged S(Q) models.
P123_D2O
  • Lyotropic liquid crystalline solutions of non-ionic ABA block copolymer Pluronic P123 in water at three concentrations: 10wt%, 30wt%, and 40wt%.
  • Suitable for testing paracrystal models.
ISIS_Polymer_Blend_TK49
  • Monodisperse (Mw/Mn~1.02) 49wt% d8-polystyrene : 51wt% h8-polystyrene polymer blend.
  • Suitable for testing Poly_GaussCoil and RPA10 models.

2D Test Data

P123_D2O
  • Lyotropic liquid crystalline solutions of non-ionic ABA block copolymer Pluronic P123 in water at three concentrations: 10wt%, 30wt%, and 40wt%.
  • Suitable for testing paracrystal models.
