Bio::FasterLmmD

A faster lmm for GWAS. GPU support coming soon.

NOTICE: this software is under active development. YMMV.

Introduction

Faster_lmm_d is a lightweight linear mixed-model solver for use in genome-wide association studies (GWAS). The original is similar to FaST-LMM (an algorithm by Lippert et al.) and that code base can be found here. Prof. Karl Broman wrote a comparison with his R/lmmlite. Faster_lmm_d and pylmm are part of the Genenetwork2 project. faster_lmm_d can parse data in R/qtl2 format as input.

Installation

In order to use the gem, you also need faster_lmm_d tool installed.

Install the gem by executing:

$ gem install bio-faster_lmm_d

Usage

bio-faster_lmm_d --geno geno_file --pheno pheno_file --ctrl ctrl_file

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
