Varia Workbench is a tool for analyzing genetic variation on a genomic scale. It can analyze tens or hundreds of thousands of genetic variations simultaneously. The program allows users to view and navigate through a visual representation of all measured variations in human chromosomes, perform genetic linkage and association tests to identify relationships between genotypes and phenotypes, view, calculate, and use haplotypes and haplotype maps, view and analyze pedigrees, and study the relationships between genetic variations, genes, and sequence regions.
