SasView Changelog

What's new in SasView 5.0.5

Feb 5, 2023
  • This is a point release which fixes some issues reported in earlier versions
  • of 5.0.x. A few highlights are:
  • The long standing issue with the Levenberg-Marquardt optimiser not respecting parameter bounds has been resolved by the move to a later version of the Bumps package.
  • A bug which prevented the radius_effective parameter from being updated in models when the data were resolution smeared has been fixed.
  • A bug that prevented the formation of composite mixture models with multiplicity (for example, models such as core_multi_shell*hardsphere + cylinder or core_multi_shell@hardsphere + cylinder) has been fixed.
  • The button to reset the selected Q-limits for fitting now works again!
  • There has been a technical change to the point in the calculation at which the volume normalisation of
  • models is applied by the move to a later version of the Sasmodels package. This change was actually incorporated into
  • v5.0.4 but due to an oversight was omitted from the release notes at the time, although a note was added to the web version after the release. In most instances this change will go un-noticed unless you happen to be plotting the
  • individual contributions of or and comparing them with similar calculations performed in versions of SasView before v5.0.4, at which point the scaling of the functions will be seen to be different.
  • There are also some new features in this version. Most notably:
  • The Generic Scattering Calculator Tool has been overhauled and its capabilities significantly expanded. In particular, it will now perform magnetic/polarised SANS computations. As part of this upgrade, coordinate data in some VTK formats are now also supported.
  • The data loaders have also been improved. SasView will now read CanSAS1D XML data files with multiple <SASdata> blocks in a single <SASentry>. And, by popular demand, 1D data can now be saved in CSV format. SESANS data files with the extension .sesans are now also recognised.
  • A Boucher-type interfacial profile function has been added to the spherical_sld model.

New in SasView 4.2.0 (Oct 8, 2018)

  • Changes:
  • The infrastucture for calculating 2D patterns from 3D orientated objects has been totally re-factored. It is now more accurate and consistent across models.
  • The way that SasView defines the orientation of anisometric and aligned objects has been completely overhauled. It now differs from previous versions.
  • Plugin models, including sum|multiply models, have completely migrated to the new infrastructure. NOTE that 3.x type models as well as early, intermediate 4.x type models, including those generated by sum|multiply will continue to be supported in 4.x but will likely no longer be supported after the move to 5.0. Users are strongly encouraged to migrate any custom models.
  • The NeXus loader has been removed as it is superseded by the NXcanSAS standard loader and SasView does not support the treatment of raw data.
  • Improvements:
  • The accuracy/speed of some numerical integrations have been improved.
  • An orientation viewer tool has been introduced to assist in understanding the new orientation framework.
  • Problems with the computation of magnetic scattering from some objects have been rectified. Some questions remain however.
  • The known issue with the core_shell_parallelepiped model is now fixed.
  • An error in the be_polyelectrolyte model was identified and rectified, but the fix is yet to be validated.
  • A number of issues and inconsistencies with the creation of sum|multiply models have been rectified.
  • A Boltzmann distribution has been added for polydispersity/orientational distributions.
  • Some batch slicing options have been introduced.
  • Correlation function analysis now computes both the 1D and 3D functions.
  • There are several data loading improvements.
  • There are several improvements to Save/Load Project.
  • The SasView version number now appears in Reports.
  • The Release Notes are now available from the program Help menu.
  • There have been numerous other bug fixes.
  • Documentation:
  • Several sections of the help documentation have undergone significant checking and updating, particularly those relating to orientation, magnetic scattering, and polydispersity distributions.
  • Detailed advanced instructions for plugin writing and some scripting instructions have also been added.
  • Concerns about the intended versus implemented meaning of some parameters in the bcc_paracrystal, fcc_paracrystal, and sc_paracrystal models have been brought to our attention. These have yet to be resolved and so a Warning has been placed on each of these models. Anyone who feels they may have the requisite expertise to investigate these concerns is strongly encouraged to contact the Developers!
  • Other Work:
  • A Third-Party initiative has recently succeeded in getting SasView to run on Debian. More details at http://trac.sasview.org/wiki/DevNotes/Projects/Debian
  • With this release we have started to prepare for the inevitable move to Python 3, which will occur with the release of 5.0
  • SasView 5.0 is currently in development. The two most significant features of this version will be (i) a move away from the present WxPython GUIs to new, completely rewritten, Qt5 GUIs, and (ii)implementation of the Beta-approximation for S(Q). Subject to resources, some limited access to the latter functionality may be available in a future SasView 4.x release.

New in SasView 4.0.0 Alpha Build 1 (Jun 30, 2016)

  • The main purpose of this major version release is a significant restructuring of the way models work to address one of the biggest issues identified by the community: the difficulty of adding complex custom models. With this release all models are essentially treated the same within the computational framework. The "built-in" models have been separated out into an independent sasmodels package. Custom models continue to be discovered by placing them in the user plugin directory. All models consist of 1 or optionally 2 files: a model.py file containing much of the details (name, parameters, etc) and either the methods for computing intensity or links to an optional model.c which contains the computational code. All models, whether from sasmodels package or in the plugins directory are treated the same by the SasView application.
  • Other things of note in this release:
  • Support for openCL means that running on macs will automatically use GPUs or multiple CPU if they exist. This is true for most windows machines as well, but in some cases the user will need to download and install the openCL drivers for their computer.
  • All model documentation has been reviewed and updated
  • A number of other minor bugs and improvement

New in SasView 4.0.0 Alpha 1 (Jun 30, 2016)

  • New sasmodels package and redesign of model code to provide:
  • polydispersity in python models
  • OpenCL support for GPU acceleration
  • simpler addition of models for users

New in SasView 3.1.2 Build 1 (Dec 10, 2015)

  • Fixes bug #468 broken remove constraint buttons in simultaneous/constrained fitting panel
  • Fixes bug #474 resulting from changes in 3.1.1 that had introduced an error in the high-Q of slit-smeared models.
  • Fixes bug #478 which would cause wx to run out of IDs and result in SasView crashing even if left alone.
  • Fixes bug #479 missing help button on simultaneous/constrained fit page
  • Fixes bug #480 GUI resizing issues on simultaneous fit page
  • Fixes bug #486 broken Report Results
  • Fixes bug #488 redraw issues in fit page

New in SasView 3.1.1 (Aug 7, 2015)

  • Fixes bug #457 that prevented SasView from starting if the user was not connected to the internet, or was behind a proxy server.

New in SasView 3.1.0 (Aug 7, 2015)

  • The documentation/help has had a complete overhaul including:
  • A completely new presentation interface (Sphinx).
  • Proof reading!
  • Updating for latest features.
  • A Help (or sometimes '?') button has been added to every panel, and some sub panels if appropriate, linking to the appropriate section in the documentation.
  • The model help has been split so that the Details button now brings up a very short pop-up giving the equation being used while HELP goes to the section in the full documentation describing the model.
  • Extensive help has also been added for the new optimizer engine (see below) including rules of thumb on how and when to choose a given optimizer and what the parameters do.
  • The optimizer engine has been completely replaced. The new optimizer still defaults to the standard Levenberg-Marquardt algorithm. However 4 other optimizers are now also available. Each starts with a set of default parameters which can be tuned. The DREAM optimizer takes the longest but is the most powerful and yields rich information including full parameter correlation and uncertainty plots. A results panel has been added to accommodate this.
  • The five new optimizers are:
  • A Levenberg-Marquardt optimizer
  • A Quasi-Newton BFGS optimizer
  • A Nelder-Mead Simplex optimizer
  • A Differential Evolution optimizer
  • A Monte Carlo optimizer (DREAM)
  • New models were added:
  • MicelleSphCoreModel (currently residing in the Uncategorized category)
  • Existing models were updated:
  • LamellarPS (bug in polydispersity integration fixed)
  • RectangularPrismModel
  • RectangularHollowPrismModel
  • RectangularHollowPrismInfThinWallsModel
  • A number of bugs were fixed including a thread crashing issue and an incorrect slit smearing resolution calculation.
  • Implemented much more robust error logging to enable much easier debugging in general but particularly the debugging of issues reported by SasView users.
