complist: Merge Peaklist And Compound ID

Description Usage Arguments Details Value Author(s) See Also

Description

This function creates a Complist object by automatically matching a Peaklist object to a PepID object. A wider matching window can optionally be defined.

Usage

1
complist(Peaklist, PepID, rtwin = 0, mzwin = 0)

Arguments

Peaklist

The Peaklist object containing peak groups from a xcms analysis

PepID

The PepID object with identified peptides

rtwin

Extension of the matching window in the retention time direction

mzwin

Extension of the matching window in the mz direction

Details

The constructor compares the mean retention time and mz values of the ID object to the minimum and maximum retention time and mz values for the peak groups. One ID can be matched to several peak groups and one peak group can be matched to several ID's if the complexity of the sample is higher than the resolving power of the LC-MS.

Value

A Complist object.
