Release Notes for v7.20

What's New in SANS Reduction Package Version 7.20 -- June 2013

Polarization procedures have been improved
Full support for the new 10m SANS instrument at NGB have been added, including SASCALC
Event mode data can now be processed through a convenient panel. Data collected in oscillatory, stream, TOF, or TISANE modes can be visualized, sliced, and processed. An XOP has been written to speed up the processing of these (often) very large files. See Event Mode Data
A panel to allow batch fitting of a single model to a large number of data sets has been implemented. It allows full control of the input guesses, data range, and held and constrained parameters. Once the starting information is gathered, the fits run unattended and save reports of the results. See: Auto Fit (or Batch Fitting)
Package loaders for processing data from various facilities have been consolidated onto the Macros menu rather than separate templates. Data handlers from different facilities cannot be loaded into the same experiment.

What's New in SANS Reduction Package Version 7.10 -- March 2012

Polarization reduction procedures have been added
Full 2D error propagation has been added. It can be exported as 2D QxQy? ASCII and used for 2D analysis in the NCNR Analysis macros or SASView.
Gravity effects have been fully included in the 2D resolution function

What's New in SANS Reduction Package Version 7.0 -- April 2010

Simulation of SANS data has been added.
Working with the Analysis models, you can now optimize the instrument setup for the expected scattering of your sample while also obtaining estimates of countrates and counting statistics in a simulated data set.
See SASCALC , Simulation of 1D SANS Data, and Simulation of 2D SANS Data.
Reduction and Analysis can now be carried out in the same Igor experiment.
Reduction and analysis modules can be loaded as needed, and hidden when no longer in use.
Patching of raw data files is now easier with improved filtering to locate files.
Reduced 1D data is now written out in canSAS standard XML format.
General arithmetic operations can now be performed on two 1D data sets, improving the former Subtract_1D operation.

What's New in USANS Reduction - Version 7.0 - April 2010

Simulation of USANS data has been added.
Similar to SASCALC for SANS, you can now adjust the angular ranges and steps, optimizing the instrument setup for the expected scattering of your sample. See UCALC and Simulation of USANS Data.
Reduced 1D data is now written out in canSAS standard XML format.
Individual raw (.bt5) files can be added together to improve statistics if a sample is re-measured at a single angular range. See Adding Raw BT5 Files.
Two full data sets (all angular ranges) can be added together to improve statistics. See Adding Two Data Sets.

What's New in SANS Analysis - Version 7.10 - March 2012

A beta version of real-space modeling has been added, allowing Debye's sphere method to be used to calculate the scattering from 3D structures in real-space.
FFT version of the calculation provides 2D information, and a binned distance method provides a much faster calculation.

What's New in SANS Analysis - Version 7.0 - April 2010

More analysis models:
Fractals with polydisperse subunits
Fuzzy spheres
bicelles
paracrystalline models (lamellar, SC, FCC, BCC)
core with multiple shells
spherocylinders
lenses
barbell
plus several empirical models, and more.
A Simple Global Fitting module has been added that is simpler to set up global fitting for the special case of two data sets, typically one USANS set and one SANS set from the same sample.
Genetic Optimization has been added as an optional search method for non-linear fitting. (Andy Nelson, ANSTO)
Reduction and Analysis can now be carried out in the same Igor experiment. Reduction and analysis modules can be loaded as needed, and hidden when no longer in use.
Reduced 1D data in canSAS standard XML format can be loaded for analysis.
Complex constraints of coefficients can be entered as well as simple bounds. See Parameter Constraints
Experimental data that has been modified (trimmed, rescaled, etc.) can be easily saved to disk.

What's New in Version 7.0 - April 2010

The original VAX planning tool SASCALC has been updated to show a graphical display of the q-range and data points that would be obtained from a selected configuration.
Simulation of SANS and USANS data has been added.
Working with the Analysis models, you can now optimize the instrument setup for the expected scattering of your sample while also obtaining estimates of countrates, counting statistics, and multiple scattering in a simulated data set.
See the help documentation for SASCALC, USANS_Simulation, Simulation of 1D (2D) SANS Data, and Simulation of USANS Data.

Future releases will include support for new instrumentation at the NCNR, including TISANE and the planned VSANS instrument.
