SasView 4.0 Alpha2 was released May 28, 2016.

What’s new in version 4.0 alpha

  • This alpha release brings a major overhaul of the model system. The new model package allows rapid integration of custom models and access to polydispersity without requiring a compiler.

  • Model package changes and improvements:

  • Model interface moved to independent sasmodels package.
  • Most models converted to new interface.
  • Allows rapid integration of user-written models.
  • OpenCL GPU utilization for faster fitting.

  • Improved numerical integration of Bessel functions.

  • SESANS integration and implementation:

  • Scripting interface added for analysis of SESANS data.
  • Hankel transformation now accepts finite acceptance angles.

  • 2D cosine transformation added for TOF SESANS analysis.

  • Documentation improvements:

  • The documentation tree was restructured for a better end user experience.
  • The documentation for each model was revamped and verified by at least two people following the conversion of the model.

  • Theoretical 1D (and 2D if applicable) scattering curves are auto-generated and added to the model documentation for each model.

  • Separation of GUI and calculations for future GUI enhancements.

  • Bug fixes:

  • Fixes bug #411 No stop button on simultaneous fit page
  • Fixes bug #410 Error with raspberry model
  • Fixes bug #364 Possible inconsistency in Poly_GausCoil model
  • Fixes bug #439 Hayter Penfold MSA code needs checking
  • Fixes bug #484 lammellerPC is precision limited
  • Fixes bug #498 $HOME/.matplotlib conflicts
  • Fixes bug #348 Control order in which fit parameters appear in the gui
  • Fixes bug #456 Provide DREAM Results Panel with something to identify data and age of results
  • Fixes bug #556 Build script improvements for developers
