PrestoPronto: a code devoted to handling large data sets

[摘要] The software PrestoPronto consist to a full graphical user interface (GUI) program aimed to execute the analysis of large X-ray Absorption Spectroscopy data sets. Written in Python is free and open source. The code is able to read large datasets, apply calibration, alignment corrections and perform classical data analysis, from the extraction of the signal to EXAFS fit. The package includes also programs with GUIs] to perform, Principal Component Analysis and Linear Combination Fits. The main benefit of this program is allow to follow quickly the evolution of time resolved experiments coming from Quick-EXAFS (QEXAFS) and dispersive EXAFS beamlines.
