SPUTNIK: an R package for peak selection of Mass spectrometry imaging data
If you find SPUTNIK useful, please consider citing our work :)
Description
SPUTNIK is an R package consisting of a series of tools to filter mass spectrometry imaging peaks characterized by a noisy or unlikely spatial distribution. SPUTNIK can produce mass spectrometry imaging datasets characterized by a smaller but more informative set of peaks, reduce the complexity of subsequent multi-variate analysis and increase the interpretability of the statistical results.
