Preparation for the computational intensive peak filling step

cPrepFillChromPeaks, cGetChromPeakData, and cFillChromPeaks are small constructs of fillChromPeaks.

By running the functions as suggested in the vignette, we minimize the RAM usage, thus making the workflow scalable to tens of thousands of files.

Usage

cFillChromPeaksStep1(input, output, fcp)

Arguments

input

path to XCMSset as returned by the peak alignment step

output

path of the output file. This file goes into cFillChromPeaksStep2()

fcp

the object returned by xcms::FillChromPeaksParam()

Value

a list object with all the necessary objects for the cGetChromPeakData and cFillChromPeaks functions
