Infrared microspectroscopy analysis training - QUASAR software

Mar 19. till Mar 20.

Infrared microspectroscopy analysis training - QUASAR software

To address the infrared user community's need for a user-friendly and open-source software for data analysis, the B22 MIRIAM beamline at Diamond Light Source in collaboration with the SMIS beamline at SOLEIL are organising a 2-day hands-on workshop to introduce the QUASAR software.

19/03/20202020-03-19 - 20/03/20202020-03-20
Diamond House, Diamond Light Source


This 2-day hands-on training will take place at Diamond Light Source and is targeted at Infrared users (current, future or potential) working on biomedical applications, material-engineering, physical-chemical sciences, and more.

The purpose of this training is to provide a practical introduction to the QUASAR software, using tutorials and examples on real-life IR microscopy (Raman) and IR imaging datasets.

What is QUASAR?

QUASAR is an open-source software for hyperspectral imaging techniques (based on the Orange machine learning and data visualization suite).

QUASAR allows user-friendly analysis using visual programming. Routine tools like baseline correction, normalization, different versions of EMSC, differentiation and smoothing can be combined with multivariate statistical and machine learning methods, such as principal component analysis or various clustering methods. Savable and shareable workflows ensure consistent analysis across different projects, or the development of different analysis to same large dataset. Visualization tools enable quick inspection of the data and the results of the analyses.


Applications are now open, and will be closing at 5pm on Tuesday 25th February 2020.
All applicants will be informed of their application outcome shortly after.
Please note that places on this training course are limited. In the case of oversubscription there will be a limit on attendees per organisation. Participants will be selected on a fair distribution basis across the research groups, giving priority to early career scientists.
If your application is successful, the workshop will be free to attend. Meals and refreshments will be provided throughout the workshop. Applicants are required to cover the cost of their accommodation and the cost of their transport to and from Diamond.
