vignette(package = "MSstatsWeightedSummary")
Major functionalities:
-
normalizeSharedPeptides
: feature-level data MSstatsTMT normalization that accounts for shared peptides -
addClusterMembership
: identification of clusters of proteins that share peptides (connected components of peptide-protein graph) -
getWeightedSummary
: protein-level summarization of feature-level data. Performed separately for each cluster of proteins and each run. Input and output compatible with MSstatsTMT workflow for analysis of mass spectrometry proteomics data with isobaric labeling.
