Description

Function to process the tissue extract of the individuals for QTL analysis

Usage

1
process_mQTL(datfile, genfile, nperm = 0)

Arguments

datfile

phenotype data

genfile

genotype data

nperm

nperm

Details

This function makes use of metabolomic and genotype data to perform QTL analysis based on the R/QTL package, for mapping quantitative trait loci. In particular, it makes use of the extended Haley-Knott method to optimize the LOD score evaluation and avoid problems with missing genotypes.

Value

2D LOD score table
