PrestoPronto is a free and open-source collection of programs aimed at performing X-ray absorption spectroscopy analysis of large data sets. The software is composed of three programs: (i) PrestoPronto_GUI, which imports spectra in various formats, pre-processes data and performs classical data analysis, (ii) LinearCom_GUI, which performs linear combination analysis, and (iii) PCA_GUI, which performs principal component analysis. All parts of the software package include practical and intuitive graphical user interfaces (GUIs) with plotting capabilities. The main objective of these programs is to quickly and interactively monitor time-resolved experiments from Quick-EXAFS (QEXAFS) and dispersive EXAFS beamlines.
