Metabolomic Quantitative Trait Locus mapping



mQTL provides a complete QTL analysis pipeline for 1H NMR data. Distinctive features include normalisation using QPN approach, peak alignment using RSPA approach, dimensionality reduction using SRV approach and finally QTL mapping using R/qtl package.

Main fucntions:

  • format_mQTL: creates the proper format of data

  • align_mQTL: peak alignment and normalisation

  • pre_mQTL: dimension reduction by statistical recoupling of variables

  • process_mQTL: computes LODs using extended Haley-Knott method

  • post_mQTL: plots the results of a given run

  • summary_mQTL: provides the results as a table
