The GAT/ML modules are now being advanced to learn human immunodeficiency virus (HIV) variation

GATACA conducts initial testing of GAT/ML on HIV patient sequences, showing that it distinguishes among major and minor HIV subtypes and recombinants, from full-length HIV genomes and the challenging envelope (env) gene.
