processStandards: Process input files containing raw data for pure standards.

In metaMS: MS-based metabolomics annotation pipeline

Description

Peak picking and further processing for raw data of pure standards, including CAMERA processing. This function is not meant to be called directly - use createSTDdbLC or createSTDdbGC instead.

Usage

processStandards(stdInfo, settings, polarity = NULL, nSlaves)

Arguments

stdInfo	Object describing the pure standards: a data.frame containing, e.g., the name of the file, the name of the standard, descriptors like CAS or Chemspider IDs, etcetera.
settings	Settings list, containing sublists for peak picking and CAMERA grouping (GC-MS) or annotation (LC-MS).
polarity	Polarity of the analysis (used for CAMERA). Possible values are “positive” or “negative”. Ignored for GC-MS.
nSlaves	Number of cores to be used in peak picking.

Value

A list of CAMERA objects resulting from the analysis of the standard injections listed in the stdInfo table.
