qtl power

Power Calculation Routines for GWAS Study Design

This is a library to quickly calculate power curves for the expected detected effect in Genome-Wide Association Studies.

Installation

If you are interested in installing this package for direct use within scripts or notebooks, please run:

git clone https://gitlab.com/data-analysis5/qtl-power.git
cd qtl-power
pip install .

to install directly from source.

Interactive Exploration via Notebooks

If you are primarily interested in a more interactive experience, you can immediately use several of our pre-built notebooks via the mybinder link above. This will allow you to use the library to generate commonly used plots for comparing power for genetic association based on mutliple input parameters.

Documentation

Currently the documentaton is held in the /docs directory and is built using Sphinx. To rebuild the documentation:

cd docsrc
make clean html copy
cd ..
git add docs/

then create a commit that will create an updated set of documentation.
