getRTdf {DIAlignR} | R Documentation

## 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
