getPeaksncGTW: Edited XCMS getPeaks for feature-wise warping functions

In ChiungTingWu/ncGTW: Alignment of LC-MS Profiles by Neighbor-wise Compound-specific Graphical Time Warping with Misalignment Detection

Description

This function is edited from getPeaks-methods to accept feature-wise warping functions.

Usage

getPeaksncGTW(object, peakrange, step = 0.1, naidx)

Arguments

object	An xcmsRaw-class object.
peakrange	matrix with 4 required columns "mzmin", "mzmax", "rtmin" and "rtmax".
step	numeric(1) defining the bin size for the profile matrix generation.
naidx	A vector contains the sample indexes need to be filled.

Details

This function is for parallelly filling missing peaks with feature-wise warping functions. The original code function in getPeaks-methods can only handle sample-wise warping functions.

Value

A list of sameple index vector and filled peak matrix.
