Dear Small-Angle Scatterers, The SasView Development Team is pleased to announce the release of SasView 4.1 The program can be downloaded from http://www.sasview.org/ This point release brings a series of new features and improvements, and a host of bug fixes. Of particular note are: - Correlation Function Analysis: This performs a correlation function analysis of one-dimensional SAXS/SANS data using Adam Washington`s CorfuncPy package. This essentially brings the capability of the old CCP13 CORFUNC package to the current generation of small-angle scatterers. - Fitting of SESANS Data: Data from Spin-Echo SANS measurements can now be loaded and fitted. The data will be plotted against the correct axes and models will automatically perform a Hankel transform in order to calculate SESANS from a SANS model. - A file converter tool for multi-file single-column data sets has been added (eg, BSL and some other SAXS instrument formats). - The way that orientation (and thereby orientational distribution) is defined is being refactored to address long standing issues and user comments. In this release, however, only models with symmetry (e.g. a=b) have been converted to the new definitions. The rest (a <> b <> c - e.g. parellelepiped) maintain the same definition as in previous versions of SasView and will be converted in SasView 4.2. Please consult the help documentation to see which definition is being used for a given model. Other enhancements include: - Support for the saving and loading of simultaneous and constrained fits - Loading of Save States from SasView v3.x.y using new sasmodel model names - Support for the saving and loading of projects with 2D fits - OpenCL is disabled by default but can be enabled through the Fitting menu option - Data and theory fields are now independently expandable - Loading a project no longer appends to an existing session but instead removes all existing data, fits, and plots Important notes: SasView 4.1 will be the last version of SasView to support native 32-bit operating systems. SasView 4.1 will probably also be the last version to support user plug-in models written for SasView versions 3.x and earlier. Any such models should now be re-written or converted to the new plug-in model architecture. Please consult the help documentation. Enjoy the program!
