Abstract
Abstract We introduce an updated and enhanced version of EASYPOP, a widely used population-genetics simulation program. The previous version (2.0.1), released in 2006, runs natively only in Windows or the old Apple PPC architecture. The new version (3.1) preserves EASYPOP’s ease of installation and use and runs natively in Windows, Linux, Apple Silicon, and Apple Intel environments. For quick re-runs, it can now write simulation parameters to and read them from a configuration file, removing the need to retype input parameters before each run. It also adds genotype output options that facilitate temporal studies by sampling any generations of interest. We also introduce an R package, easypopr, that further automates running EASYPOP 3.1 using R commands to easily setup and rerun simulations with changes in parameters. easypopr provides tools to visualize the effects of different parameter choices (Ne, mutation models, migration rates, demographic scenarios, etc.) on summary statistics, including subpopulation mean heterozygosity (Hs), total metapopulation heterozygosity (HT), FIS, FST, and Ne-estimates. Outputs from easypopr (and EASYPOP) are easily fed into snpR or other R packages for convenient, wide-ranging analysis to quantify the effects of demography on the power to detect genetic change, including integration with programs like NeEstimator and STRUCTURE. With these enhancements, available in executables for all common operating systems, EASYPOP 3.1 provides a streamlined approach for conducting forward-time genetic simulations across a wide range of scenarios.
