• Inthinnerator, a program for thinning genetic variants using a recombination map. Read the inthinnerator documentation.
• HPTEST, a program for testing for association between host and parasite genotypes. See the wiki page for more details.
• LDBird, a program for computing LD metrics between all pairs of variants in a genomic region or across whole genomes. See the wiki page for more details.
