 This module provides support and visualization of genotypic data stored in a modified GMOD Chado schema. The 3.x branch of this module represents a shift towards support for large scale genotypic datasets through backwards compatible improvements to the Chado schema including a new gathering table for genotypes (genotype_call) modeled after the Chado phenotype table, optimized queries and well-chosen indexes.
