import.msfinder.formulas: import.msfinder.formulas

In RAMClustR: Mass Spectrometry Metabolomics Feature Clustering and Interpretation

import.msfinder.formulas

Description

After running MSFinder on .mat or .msp files, import the formulas that were predicted and their scores

Usage

import.msfinder.formulas(ramclustObj = NULL, mat.dir = NULL, msp.dir = NULL)

Arguments

ramclustObj	R object - the ramclustR object which was used to write the .mat or .msp files
mat.dir	optional path to .mat directory
msp.dir	optional path to .msp directory

Details

this function imports the output from the MSFinder program to support annotation of the ramclustR object

Value

new slot at $msfinder.formula.details
