AquaSplatche is a program to simulate genetic diversity based on a realistic vectorized environment. Simulate genetic diversity with this tool.

Classical models of structured populations do not apply well to populations of freshwater fishes, since they evolve in complex networks of river systems that are intermediate between one-dimensional and two-dimensional stepping-stone models. In order to allow the simulation of the genetic diversity of populations drawn from such river systems, we have developed a new simulation program called AQUASPLATCHE. It starts by dividing a realistic vectorized network of river streams into segments of arbitrary length. The program then proceeds by simulating the colonization of the streams from an arbitrary source, recording the evolution of the segment densities and the migration events between adjacent segments over time. This demographic history is then used to generate genetic data of population samples located in various segments of the river system, using a backward coalescent framework.

To run AQUASPLATCHE, the compressed file needs to be extracted and copied to an arbitrary directory. "AQUASPLATCHE.exe" is the main executable file and can be started by a double-click. The graphical settings are stored in a settings file, to store them between different sessions.
