SPUTNIK: an R package for peak selection of Mass spectrometry imaging data

If you find SPUTNIK useful, please consider citing our work :)

Inglese, P., Correia, G., Takats, Z., Nicholson, J. K. & Glen, R. C. (2018). SPUTNIK: an R package for filtering of spatially related peaks in mass spectrometry imaging data. Bioinformatics (Oxford, England).


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.


Install from CRAN

To install the CRAN package, run the command:
