       SasView is software for the analysis of Small-Angle Scattering (SAS) data.

       It  fits analytic functions describing different types of material microstructure to experimental data in
       order to determine the shape, size and degree of ordering.

       SasView also includes tools for calculating scattering length densities, slit sizes,  resolution,  fringe
       thicknesses/d-spacings, the (Porod) invariant ('total scattering'), and distance distribution functions.

       sasview - SasView Documentation

NOTE:
          In Windows use [Alt]-[Cursor left] to return to the previous page

   MenuBar
       The menu bar at the top of the SasView window gives you access to additional features of the program:

   File
       The File option allows you load data into SasView for analysis, or to save the work you have been doing.

       Data  can be loaded one file at a time, or by selecting multiple files, or by loading an entire folder of
       files (in which case SasView will attempt to make an intelligent guess as to what to load  based  on  the
       file formats it recognises in the folder!).

       A  SasView  session can also be saved and reloaded as an ‘Analysis’ (an individual model fit or invariant
       calculation, etc), or as a ‘Project’ (everything you have done since starting your SasView session).

   Edit
       The Edit option allows you to:

       • undo/redo your recent changes;

       • copy and paste parameters between SasView analysis windows;

       • copy parameters from  a  SasView  analysis  window  to  the  Clipboard  as  either  tab-delimited  text
         (compatible with Microsoft Excel) or LaTex-wrapped text;

       • generate a summary ‘Report’ of the most recent analysis performed;

       • reset parameter values in the P(r) Inversion analysis page.

   View
       The View option allows you to:

       • show the Batch Fitting Results Panel if it has been closed;

       • show/hide the Data Explorer Panel;

       • show/hide the Toolbar of icons below the Menu Bar;

       • select  the  default  location  that  SasView  looks  in  for data to analyse (the SasView installation
         directory, the initial default, or a custom folder). NB: any change only takes effect when  SasView  is
         restarted;

       • change  the  default assignment of categories (Shapes, Shape-independent, StructureFactor) for fitting
         model functions.

   Tools
       The Tools option provides access to a comprehensive range of tools and  utilities.  See  tools  for  more
       information.

   Window
       The Window option allows you to select which SasView windows are visible.

   Analysis
       The Analysis option provides access to the key functionality of SasView:

       • Model Fitting;

       • P(r) Inversion;

       • Invariant Analysis;

       • Correlation Function Analysis (SasView 4.1 and later)

       See analysis for more information.

   Fitting
       The Fitting option allows you to:

       • create a new FitPage;

       • change optimiser (under Fit Options);

       • view fit parameter correlations, distributions, and convergence traces (under Fit Results);

       • create/edit a Plugin Model.

       Additional  functionality  is  available under this menu option during particular types of model fitting,
       including:

       • setting up a Constrained or Simultaneous Fit;

       • combining a Batch Fit (an obscure capability);

       • setting up Chain Fitting.

   Help
       The Help option provides access to:

       • this help documentation;

       • a tutorial on using SasView (in pdf format);

       • information on how to acknowledge SasView in publications;

       • information about the version of SasView you are using;

       • the marketplace;

       • a check to see if there is a more recent version of SasView.
