These software packages all produce or consume tree sequences in the .trees file format.

Simulate

Create tree sequences from models of biological processes

Simulate genealogical trees and genomic sequence data using population genetic models

ts = msprime.sim_ancestry(
    samples=10, 
    recombination_rate=1e-4, 
    sequence_length=1e6
)
ts = msprime.sim_mutations(ts, rate=1e-6)

SLiM is a genetically explicit forward simulation software package for population genetics and evolutionary biology. It is highly flexible, with a built-in scripting language, and has a cross-platform graphical modeling environment called SLiMgui.

    initializeTreeSeq();
    initializeMutationRate(1e-8);
    initializeMutationType("m1", 0.5, "e", 0.001);
    initializeGenomicElementType("g1", m1, 1.0);
    initializeGenomicElement(g1, 0, 999999);
    initializeRecombinationRate(1e-8);
}
