SansView 1.0

New application for SANS oriented system modeling and data analysis.

Oct 2009: version 1.0 is released.

Roadmap:

SansView is a new application provided to the community to generate feedback. It is part of a broader effort to provide analysis tools to the SANS community. In providing this application, we hope to learn about the analysis needs of our users. We are interested in suggestions in two areas:
  • Functionality: what functionality would you like to see in an analysis application for SANS
  • Ease-of-use: how would you improve the user interface
The functionality provided by SansView will be incorporated in a more complete analysis application scheduled for early 2010. SansView will continue to be supported and updates will mostly focus on both new features and bug fixing. See our Mission page for more details on the plans for future developments.

What's new in version 1.0:

  • Implemented P(r) inversion (Indirect Fourier transformations).
  • Improved fitting and model caculation speed by a factor of ten.
  • Supporting many more model functions.
  • Supporting P(Q)*S(Q) for most of the shape based form factors.
  • Added more distribution functions for the polydispersion calculations.
  • Added a bookmarking feature so that the results of the calculation can be recalled later.
  • Q range reset button is added.
  • Added a color bar in 2D data plots.
  • Added a model function detail button for an easy access to the model help from the fitting panel.
  • And much more.

What's new in the previous versions:

  • Fixed problem with 1D data fitting that took dI = 1 (instead of taking it from dI data).
  • Fixed problem with the polydispersity for P(Q)*S(Q) functions.
  • Simultaneous fit of a number of different sets of SANS data with/without the constraints.
  • 1D and 2D data fitting using Scipy or Park (a MC fitting optimizer) fitting engine.
  • Supporting a number of standard model and model-independent functions including form factor and structure factor functions, and available some of their multiplications.
  • Supporting various 2D averaging methods : Circular, Sectorslicer, Annulus, Boxsum, BoxQx and BoxQy.
  • Advanced additional features; supporting instrumatal smearing, slit smearing, and polydispersity and orientational distribution for shape based models.
  • 2D data manipulation and modeling.
  • User defined Qrange (Qmin and Qmax) for both 1D and 2D data for fitting and modeling.
  • Loading and displaying 1D and 2D data of various formats.
  • Plug-in mechanism for data readers.
  • Easy pop-up menu by mouse clicking on a given plot.
  • Users arrange the various windows.
  • The user can toggle between a number of different scales on all plots.
  • Support saving data in the formats of ASCII(txt) and xml.

Installation and Usage:

  • Currently supported only on Windows : Windows XP, Vista.

    • (Notes for Wine (Linux/Mac) users.)
