Description
FDA (Fast Data Analyser) is an application developed at ALBA Synchrotron to analyse the data produced with X-ray Absorption Spectroscopy (XAS), as well as with X-Ray Diffraction (XRD). It provides a quick and convenient way of loading, processing, and analysing the data with different methods, such as XANES (X-ray absorption near edge structure) normalization, EXAFS (Extended X-ray absorption fine structure) extraction and Fourier Transforming, LCA (Linear combination analysis), PCA (Principal component analysis), or MCR (Multivariate Curve Resolution). Raw data from transmission, fluorescence, and electron yield experiments can be loaded and preprocessed in different ways, including: deglitching, self-absorption correction, or background subtraction. With this versatile tool utilizing multiple numerical algorithms, the user can perform quick calculations with selected technique, extract analysis results together with plots, and export them externally in various formats.
FDA is a user-friendly application that comes with a full-featured forms-based environment for interacting with and processing the data implemented using PyQt toolkit. It is currently capable of loading hundreds of spectra at once and provides access to a number of features of XAS & XRD techniques, making it a robust & flexible tool for any type of analysis. Already in use at several spectroscopy-oriented beamlines at ALBA Synchrotron, it provides a simple yet powerful way of quickly analysing the data produced in the experiments.
