bcMVNmtQTL {FastMtQTL}R Documentation

Regression based fast multi-trait genome-wide QTL analysis using the properties of multivariate normal (MVN) distribution.

Description

This function calculates the LOD (log of odds) for multi-trait QTL analysis using the properties of multivariate normal distribution.

Usage

bcMVNmtQTL(inData, phenoCols, Chrs, markerInterval=1.01)

Arguments

inData

Input data set for multi-trait QTL analysis.

phenoCols

Column numbers in the phenotype matrix which should be used in the analysis.

Chrs

Vector of chromosome number(s) for which LOD scores should be calculated.

markerInterval

Maximum distance (in cM) between positions at which the genotype probabilities are calculated, though for step = 0, probabilities are calculated only at the marker locations.

Value

It will return a dataframe with the values of log of odds (LOD) statistic for multi-trait QTL mapping.
