format_mGWA {mQTL.NMR} | R Documentation

## Routine to reformat the data into the required format to perform mGWAS

### Description

This function enables to reformat data into the proper format. The user should provides in input metabolomic file, Genotype file, map file and a file containing sex, age and individual IDs.

### Usage

    format_mGWA(datafile, genofile1, genofile2, covarfile, outdat, outgeno)

### Arguments

`datafile` | metabolomic data file
`genofile1` | genotype file in the "ped" format
`genofile2` | map file containing more information on SNP marker (position, ...)
`covarfile` | a text file contains covariates such as age or sex
`outdat` | output data file with formatted phenotype data in csvs format
`outgeno` | output data file with formatted genotype data in csvs format

### Value

formatted phenotype and genotype data files (in format csvs) are written to the user working directory (it is therefore preferable that the user create a new directory to be used throughout the study)
