In singjc/mstools: OpenSWATH Mass Spectrometry Data Exploration

Description

This function can be used to extract information from the PQP library file. This can also be used to extract the transition informaiton from and OSW results file.

Usage

getPepLibData_(libfile, peptide_id = "", mod_peptide_id = c("", ""))

Arguments

libfile	A character vector of the absolute path and filename of the library file. (Must be .pqp format)
peptide_id	A character vector for extraction of a specific peptide. I.e. 'ANSSPTTNIDHLK'
mod_peptide_id	An array of two string vectors indicating a specific modified peptide sequence with both UniMod annotation and actual modification name to extract information for. I.e. c(ANS(Phos)SNSLK, ANS(UniMod:21)SNSLK) (Default: ”)
