  "Description": "MsCoreUtils defines low-level functions for mass\nspectrometry data and is independent of any high-level data\nstructures. These functions include mass spectra processing\nfunctions (noise estimation, smoothing, binning, baseline\nestimation), quantitative aggregation functions (median polish,\nrobust summarisation, ...), missing data imputation, data\nnormalisation (quantiles, vsn, ...), misc helper functions,\nthat are used across high-level data structure within the R for\nMass Spectrometry packages.",
