merge_ibaq: Merge iBAQ intensities

In arnesmits/DEPstoi: Stoichiometry analysis of label-free proteomics data

Description

merge_ibaq generates a data.frame with merged iBAQ intensities for proteins with shared peptides.

Usage

merge_ibaq(proteins_unique, peptides)

Arguments

proteins_unique	Data.frame, Protein table with unique names annotated in the 'name' column.
peptides	Data.frame, Peptides table from MaxQuant ('peptides.txt').

Value

A data.frame with iBAQ intensities per protein group. Every protein group contains peptides unique to this group.

Examples

# Use example data
data <- GFPip
peptides <- GFPip_pep

# Make unique identifiers
data_unique <- make_unique(data, 'Gene.names', 'Protein.IDs')

# Merge iBAQ intensities
ibaq <- merge_ibaq(data_unique, peptides)

colnames(ibaq)
head(ibaq)
