SasView version 3.1.2
New in Version 3.1.2
This release is a major stability improvement, having fixed a serious bug that came to light since release 3.1.1. All users should upgrade.
- 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 Version 3.1.1
- 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 Version 3.1.0
- 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)
- The five new optimizers are:
- 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.
