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 test data sets are organized based on their data structure:

  • 1D data
  • 2D data
  • coordinate data
  • image data
  • SESANS data
  • save states
  • upcoming formats

1D Data

1D data sets EITHER have:

  • at least two columns of data with I(Q) (assumed to be in absolute units) on the y-axis and Q on the x-axis. And additional columns of data may carry uncertainty data, resolution data, or other metadata.

OR:

  • the I(Q) and Q data in separate files with no other information.

Data in the latter format need to be converted to a single file format with the :ref:`File_Converter_Tool` before they can be analysed in SasView.

?

1D Test Data

33837rear_1D_1.75_16.5
  • Data from a magnetically-oriented surfactant liquid crystal output by the Mantid framework. The data was collected on the SANS2D instrument at ISIS.
10wtAOT_Reline_120_reduced / Anton-Paar_PDH / saxsess_example
  • Data from Anton-Paar SAXSess instruments saved in Otto Glatter's PDH format.
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.
APS_DND-CAT
  • ASCII data from the DND-CAT beamline at the APS.
APS_X / APS_Y
FIT2D_I / FIT2D_Q
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.
ISIS_83404 / ISIS_98929
  • Polyamide-6 fibres hydrated in D2O exhibiting a broad lamellar peak from the semi-crystalline nanostructure.

  • This is the same data as that in Z8300* / Z9800* but in an amalgamated ASCII format!

  • Suitable for testing :ref:`Correlation_Function_Analysis` .

    ?
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.
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.
Z8300*.I1D / Z8300*.QAX / Z9800*.I1D / Z9800*.QAX
  • BSL/OTOKO data from polyamide-6 fibres hydrated in D2O exhibiting a broad lamellar peak from the semi-crystalline nanostructure.

  • This is the same data as that in ISIS_83404 / ISIS_98929 but in an older separated format!

  • Suitable for testing the :ref:`File_Converter_Tool` .

    ?
  • Suitable for testing :ref:`Correlation_Function_Analysis` .

2D Data

2D data sets are data sets that give the reduced intensity for each Qx-Qy bin. Depending on the file format, uncertainty data and metadata may also be available.

2D Test Data

33837rear_2D_1.75_16.5
  • Data from a magnetically-oriented surfactant liquid crystal output by the Mantid framework. The data was collected on the SANS2D instrument at ISIS.
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.

Coordinate Data

Coordinate data sets, such as PDB or OMF files, and which describe a specific structure, are designed to be read and viewed in the :ref:`SANS_Calculator_Tool` .

?

Coordinate Test Data

A_Raw_Example-1
  • OMF format data file from a simulation of magnetic spheres.
diamond
  • PDB format data file for diamond.
dna
  • PDB format data file for DNA.
sld_file
  • Example SLD format data file.

Image Data

Image data sets are designed to be read by the :ref:`Image_Viewer_Tool` . They can be converted into synthetic 2D data.

?

Image Test Data

ISIS_98940
  • Polyamide-6 fibres hydrated in D2O exhibiting a broad lamellar peak from the semi-crystalline nanostructure.
  • Data is presented in Windows Bitmap (BMP), GIF, JPEG (JPG), PNG, and TIFF (TIF) formats.

SESANS Data

SESANS (Spin-Echo SANS) data sets primarily contain the neutron polarisation as a function of the spin-echo length. Also see :ref:`SESANS` .

?

SESANS Test Data

spheres2micron
  • SESANS data from 2 micron polystyrene spheres in 53% H2O / 47% D2O.

Save States

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 (.prv), or invariant calculation (.inv). A project file (.svs) contains the results for every active analysis in a SasView session.

Saved State Test Data

fitstate.fitv
  • a saved fitting analysis.
test.inv
  • a saved invariant analysis.
test002.inv
  • a saved invariant analysis.
prstate.prv
  • a saved P(r) analysis.
newone.svs
  • a saved SasView project.

Upcoming Formats

Data in this folder are in formats that are not yet implemented in SasView but which might be in future versions of the program.

radius_dist.txt
