glycoChainSaw: A function to modify a chainsaw in silico digest

In MargaretBaker/plantGlycoMS: A package for processing plant glycosylation MS data

Description

this function adds the mass for carbamidomethylation and methionine oxidation and filters for glycopeptides

Usage

glycoChainSaw(digest.N, digest.n, carbamidomethylation = TRUE,
  methionineOxidation = TRUE, glycoOnly = TRUE)

Arguments

digest.N	a chainsaw in silico digest with all glycosylation sites having a capital n (N)
digest.n	a chainsaw in silico digest with all glycosylation sites having a lower case n (n)
carbamidomethylation	57 Da is added to the peptide mass for every cysteine present, default=TRUE
methionineOxidation	16 Da is added to the peptide mass for every methionine present, and a new row is added to the table so that every methionine containing peptide has a value for oxidized and not oxidized, default=TRUE
glycoOnly	return a dataframe containing only data for peptide with glycosylation sites, default=TRUE

Examples
