Advanced Infrared Microspectroscopy Analysis Training - QUASAR software

Mar 23. till Mar 25.

Advanced 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.

Date
23/03/20212021-03-23 - 25/03/20212021-03-25
Location
Online (Via Zoom)

Overview

This 2-day advanced hands-on training will take place online, on the 23rd and 25th March 2021, 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 an advanced training 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.
