Description

Takes a metabolite info table from the ConsensusAlign output and annotates with the Feihn library

Usage

1
2
FeihnMatch(PeakInfoTable, FeihnLibrary, numCores = 4, commonIons = c(),
  RT1_Standards = NULL, RT1Penalty = 1)

Arguments

PeakInfoTable

Metabolite info table (the second data frame in the output from ConsensusAlign)

FeihnLibrary

Provide Feihn library generated from MakeReference function to ID metabolites with retention index. (Use data(FeihnStandards_030617) to find)

numCores

Number of cores used to parallelize alignment. See parallel package. Defaults to 4.

commonIons

Provide a vector of ions to ignore from the FindProblemIons function. Defaults to empty vector.

RT1_Standards

Vector of standard names used to adjust first retention time. All names must be found in input files. Defaults to NULL.

RT1Penalty

Penalty used for first retention time errors. Defaults to 1.

Value

A new metabolite info file with three columns appended to that are the top three Feihn library matches
