SPIKE a Processing Software dedicated to Fourier Spectroscopies

Abstract: We present SPIKE (Spectrometry Processing Innovative KErnel), an open-source Python package dedicated to Fourier spectroscopies. It provides basic functionalities such as apodisation, a complete set of Fourier transforms, phasing for NMR), peak-picking, baseline correction and also tools such as Linear Prediction. Beside its versatility, the most prominent novelty of this package is to incorporate new tools for Big Data processing. This is exemplified by its ability to handle the processing and visualization of very large data-sets, with multiprocessor capabilities and a low memory footprint. The software contains also all the tools necessary for the specific fast processing and visualization of 2D-FTICR-MS data-sets.
