getRTdf: Calculates global alignment between RT of two runs

In shubham1637/DIAlign: Dynamic Programming Based Alignment of MS2 Chromatograms

Calculates global alignment between RT of two runs

Description

This function selects features from oswFiles which has m-score < maxFdrLoess. It fits linear/loess regression on these feature. Retention-time mapping is established from reference to experiment run.

Usage

getRTdf(features, ref, eXp, maxFdrGlobal)

Arguments

features	(list of data-frames) it is output from getFeatures function.
ref	(string) Must be a combination of "run" and an iteger e.g. "run2".
eXp	(string) Must be a combination of "run" and an iteger e.g. "run2".
maxFdrGlobal	(numeric) A numeric value between 0 and 1. Features should have m-score lower than this value for participation in global fit.

Value

A data-frame
