Data reduction and analysis

Data analysis is supported through user training which is provided at the AINSE Neutron Scattering Winter Schools.  Other workshops may be periodically advertised here.

To correct, reduce and analyse experiment data from Quokka, the Igor Pro software from WaveMetrics is used and extended with specially designed macros to simplify the process.

Igor Pro can be downloaded from WaveMetrics home page . A trial version is available which allows the free use of Igor Pro for 30 days. After Igor Pro has been installed and tested, ANSTO’s Small Angle Neutron Scattering (SANS) reduction macros can be installed with the switch program.

ANSTO’s SANS reduction macros are based on the SANS & USANS macros from NIST, which can be found at the NIST SANS homepage.  Although these macros contain an option to reduce Quokka data, the instrument information is not current and it is not advised to use these macro’s for Quokka data reduction.  It is advised to use the switch program to install the macro's. 

Users who wish to utilize SANS macros provided by ANSTO or NIST are requested to reference the paper by Steve Kline describing the software.

For support, contact the Quokka instrument scientists:


Many packages are available for the analysis of SANS data in addition to macros operating in Igor. Some generally useful packages are:

There are many more specialized packages. It suggested to ask your local contact for guidance.

Data Access

The Australian Centre for Neutron Scattering  promotes access to data collected during scientific experiments. See

Access to data is available at ANSTO during the 3 year embargo period via the following options:

If you are unable to login, contact the  User Office. 

It is ANSTO policy that after a 3 year embargo period, data becomes publicly accessible. This can be viewed as "Public Experiments" at Metadata relating to the experimental data is copied to Research Data Australia In encouraging this practice ANSTO has helped many researchers forge new collaborations.
