SPS: Forward-Backward Spatial Simulator for Genetic Data

We have implemented an open source software, named sps, which can be used for obtaining samples from a population that lives in a complex environment, and enable us to study the statistical properties of samples and perform hypothesis testing (e.g. neutrality vs selection) or parameter inference. Different regions of the environment may have unique characteristics. sps efficiently simulates genetic polymorphisms using a forward-backward in time approach.
