pophelper is an R package and web app to analyse and visualise population structure.
pophelper curently supports output run files generated from population analysis programs such as STRUCTURE, TESS, TESS3, BAPS and numeric delimited formats such as ADMIXTURE or fastSTRUCTURE. The
pophelper package can be used to read run files to R, tabulate runs, summarise runs, estimate K using the Evanno method, align clusters within K using CLUMPP, export files for DISTRUCT and generate barplot figures.
You need to have R (> 3.4.0) statistical package installed on your system. R is open-source and freely available to download for Windows, Mac and other OS. Then, install the dependency packages. Then, you can install
github using the
# install dependencies and devtools install.packages(c("Cairo","ggplot2","gridExtra","gtable","tidyr","devtools"),dependencies=T) # install pophelper package from GitHub devtools::install_github('royfrancis/pophelper') # load library for use library(pophelper)
pophelper 1.2.0 and later includes binary executables for CLUMPP and DISTRUCT. This is experimental and may not work on all OS and versions.
pophelper has been tested on the following systems:
An online interactive version of pophelper is available at pophelper.com. The web app is quite outdated and limited in terms of functionality and flexibility. The web app must not be used for major work or large datasets. The web app is also limited in computational power and working hours. The web app will be automatically restricted after 100 hours of use per month. If anyone has ideas for funding
pophelper web server, please get in touch.
