Irena & Nika software courses
organized by
Advanced Photon Source, Argonne National Laboratory
in support of World-wide materials science, physics,
chemistry, and polymers SAXS/SANS community
Next APS workshop is planned for 18-19 September 2014, registeration.
To request to be put on waiting list for next one (January 2015?) send e-mail to Connie.
Thinking about running this course at your facility/event? Make proposal. In November 2012 we had course at Australian Lightsource and in February 2013 at Brazilian Lightsource.
Successful small-angle x-ray scattering (SAXS) experiment requires appropriate data reduction and analysis tools. Igor Pro based packages Nika (for SAXS data reduction) and Irena (for SAXS data analysis) were developed during the last 10 years at the APS. They are already being used widely for material science, physics, and chemistry SAXS at the APS and at other facilities worldwide. These tools are commonly taught during "Beyond Rg" - SAXS short course organized semi-annually by APS SAXS SIG (next one scheduled for March 2012). However, the main audience of the SAXS short course is new SAXS users, starting with their own SAXS program and therefore it focuses more heavily on experiments, theory etc. The time devoted in this course for software is insufficient for experienced experimenters interested in complex software applications.
Therefore, the APS SAXS Special Interest Group (SIG) is organizing this specialized, hands-on, course specifically on the SAXS software Nika and Irena. The course will be taught by the software author, Jan Ilavsky, APS staff member. In order to provide high educational value, the number of participants will be limited to 20. Participants are expected to have a high level of SAXS experience and bring their own computers (Windows or OSX). In addition, they are encouraged to bring their own SAXS experimental results.
NOTE: This course is NOT for bioSAXS (protein structure and similar mono dispersed systems), the Irena software is mostly suitable for polydispersed and complex (hierarchical) systems. If you are not sure if your scientific application fits in the scope of this software, please ask.
Link to materials for participants (0.6 Gb zip file!) : CourseMaterials These are materials provided to particpants at the start of the course for copy from usb stick. These materials are for particpants wholost their own copy. If you need just installers or selected files (handouts etc.), they are available on http://usaxs.xray.aps.anl.gov.
Prior courses typically had 16 - 20 participants each.
