find_shared_prots: Finds peptides that are shared by proteins.

In qzhang503/proteoQ: Processing and Informatic Analysis of Mass Spectrometrirc Data

Finds peptides that are shared by proteins.

Description

Only for PSM tables where the same pep_seq duplicated in rows with different prot_acc's . This for now means Mascot with same-set and sub-set proteins enabled. Otherwise, e.g. when applying to other search engines without such redundancy, every peptide would turn out to be unique.

Usage

find_shared_prots(df = NULL, pep_id = "pep_seq", prot_id = "prot_acc")

Arguments

df	PSM data.
pep_id	the column key of peptide sequences.
prot_id	The column key of protein accessions.

Details

Output rows are unique at the levels of c("prot_acc", "pep_seq"). By default, sequences of Protein terminals will be treated separately.
