MSstatsWeightedSummary: Weighted Protein-Level Summarization for Protein Clusters

Installation:

if (!require(devtools)) {
    install.packages("devtools")
}
devtools::install_github("Vitek-Lab/MSstatsWeightedSummary")

Getting help:

?getWeightedProteinSummary
?normalizeSharedPeptides
?addClusterMembership
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.
