manual.annotation.template: manual.annotation.template

In RAMClustR: Mass Spectrometry Metabolomics Feature Clustering and Interpretation

manual.annotation.template

Description

export a .csv formatted template for manually editing MSFinder annotations

Usage

manual.annotation.template(
  ramclustObj = NULL,
  outfile = "manual.annotation.template.csv"
)

Arguments

ramclustObj	ramclustR object to annotate
outfile	output file directory and name. default = 'manual.annotation.template.csv'

Details

While unsupervised annotation is rapid and objective, subjective knowledge can be used to improve annotations. This function writes a template file containing compound name, computationally assigned inchikey, and an empty column for your manually inferred inchikey. Upon completion of manual annotation, you can reimport this file and update your ramclustR object to reflect your manual input.
