International Conference on X-Ray Absorption Fine Structure


Larch for XAFS data processing and Analysis

XAFS 2021 Virtual is offering a Virtual Hands-on Tutorial /Demo using Larch for XAFS data processing and analysis. Please note, this is not included in your XAFS 2021 Virtual registration fee, an additional cost of $50 will be added to your invoice.

To be able to cater for all time zones, the same workshop will be offered twice on Sunday 11 July during the following timeslots:

  1. 10.00 – 13.00 AEST
  2. 15.00 – 1800 AEST

Larch provides a full range of tools for processing, visualizing, and analysing XAFS Data. In this workshop, we'll demonstrate basic data processing of XANES and XAFS data, including the fitting of pre-edge peaks, principal component analysis, and linear combination analytic methods. For analysis of the extended EXAFS, background subtraction and Fourier transforms will be demonstrated and discussed. Simple examples of fitting one and two paths from Feff calculations will also be demonstrated. The analyses shown will be a combination of Graphical User Interface and scripting and programming with the Larch Python library will be discussed.
