Pre-processing of Mzion PSM tables

Description

Pre-processing of Mzion PSM tables

Usage

preMZpepLFQ(
  df = NULL,
  group_psm_by = "pep_seq_mod",
  group_pep_by = "prot_acc",
  dat_dir = NULL,
  set_idx = 1L,
  injn_idx = 1L,
  tmt_plex = 1L,
  rm_allna = FALSE
)

Arguments

df

A data frame.

group_psm_by

A character string specifying the method in PSM grouping. At the pep_seq default, descriptive statistics will be calculated based on the same pep_seq groups. At the pep_seq_mod alternative, peptides with different variable modifications will be treated as different species and descriptive statistics will be calculated based on the same pep_seq_mod groups.

group_pep_by

A character string specifying the method in peptide grouping. At the prot_acc default, descriptive statistics will be calculated based on the same prot_acc groups. At the gene alternative, proteins with the same gene name but different accession numbers will be treated as one group.

dat_dir

A working directory.

set_idx

A set index.

injn_idx

An injection index.

rm_allna

Logical; if TRUE, removes data rows that are exclusively NA across ratio columns of log2_R126 etc. The setting also applies to log2_R000 in LFQ.

TMT_plex

The multiplexity of TMT.
