Dataset Information

SPUTNIK: an R package for filtering of spatially related peaks in mass spectrometry imaging data.

ABSTRACT:

Summary

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.
