In yguitton/metaMS: MS-based metabolomics annotation pipeline

Construct an object containing all meta-information of the annotated pseudospectra (GC-MS).

Description

Function getFeatureInfo yields a data.frame with meta-information on all features detected in the samples. Features are rows; information is in the columns. Not meant to be called directly by the user.

Usage

getFeatureInfo(stdDB, allMatches, sampleList)

Arguments

stdDB	In-house database of standards.
allMatches	Object containing annotation information, generated by functions like matchSamples2DB and matchSamples2Samples.
sampleList	Object containing pseudospectra of samples.

Value

A data.frame summarizing all meta-information of the pseudospectra found in the samples. Exactly what columns are included depends on the information contained in the in-house database. The last column is always "rt".
