All of the sections above are provided as processed markdown files. Clicking the link should display a web readable page with text, a few select commands and plots and tables. The code used to generate these pages is provided in the corresponding .Rmd file. If you would like to run the code in these files yourself you will need to;

1. Checkout this repository

git clone https://github.com/iracooke/atenuis_wgs_pub.git

2. Download additional data not hosted on github due to size constraints

cd atenuis_wgs_pub
wget http://data.qld.edu.au/public/Q5999/iracooke/atenuis_wgs_pub/data.tgz -O data.tgz
tar -zxvf data.tgz 

3. Open the project file atenuis_wgs_pub.Rproj in RStudio and open the desired file (eg 01_population_structure.Rmd). After installing any required R packages the code should run and produce plots and tables identical to those shown in the web links above.
