FaST-LMM

FaST-LMM, which stands for Factored Spectrally Transformed Linear Mixed Models, is a program for performing genome-wide association studies (GWAS) on datasets of all sizes, up to one millions samples.

This release contains the following features, each illustrated with an IPython notebook.

• Core FaST-LMM (notebook) -- Lippert et al., Nature Methods 2011

Improvements:

• New features for single_snp (including effect size and multiple phenotype support) and epistasis (including reporting beta and using pre-computed eigenvalue decompositions) (notebook) -- Lippert et al., Nature Methods 2011
• Ludicrous-Speed GWAS (notebook) -- Kadie and Heckerman, bioRxiv 2018
• Heritability with Spatial Correction (notebook), Heckerman et al., PNAS 2016
• Two Kernels (notebook) -- Widmer et al., Scientific Reports 2014
• Set Analysis (notebook) -- Lippert et al., Bioinformatics 2014
• Epistasis (notebook) -- Lippert et al., Scientific Reports, 2013
• Prediction (notebook) -- Lippert et al., Nature Methods 2011

A C++ version, which is generally less functional, is available. See http://fastlmm.github.io/.

Quick install:

pip install fastlmm

If you need support for BGEN files, instead do:

pip install fastlmm[bgen]

For best performance, be sure your Python distribution includes a fast version of NumPy. We use Anaconda's Miniconda.
