isolatePeaks: isolatePeaks

In Autotuner: Automated parameter selection for untargeted metabolomics data processing

Description

This function is designed to handle the isolation of TIC peak regions to throw into AutoTuner.

Usage

isolatePeaks(Autotuner, returned_peaks, signals)

Arguments

Autotuner	An Autotuner object. Ideally generated right after signal processing peak identification is complete.
returned_peaks	A numerical value representing the number of peaks that are to be returned to the user for downstream parameter optimization.
signals	A list of list containing data from sliding window analysis.

Value

Returns an Autotuner object with selected TIC regions.

Examples

Autotuner <- readRDS(system.file("extdata/Autotuner.rds",
package="Autotuner"))
lag <- 25
threshold<- 3.1
influence <- 0.1
signals <- lapply(getAutoIntensity(Autotuner), ThresholdingAlgo,
lag, threshold, influence)
isolatePeaks(Autotuner, returned_peaks = 10, signals)
