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
- convertible 1D data files
- 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. Test files are located in the /convertible_files folder.
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 / 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.
- 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 the BSL/OTOKO Z8300* / Z9800* files 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.
Convertible 1D Data
- APS_X / APS_Y
ASCII data output by a reduction software package at the APS.
Suitable for testing the :ref:`File_Converter_Tool` .
- FIT2D_I / FIT2D_Q
ASCII data output by the FIT2D software package at the ESRF.
Suitable for testing the :ref:`File_Converter_Tool` .
- 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
