Michigan Imputation Server

Michigan Imputation Server provides a free genotype imputation service using Minimac4. You can upload phased or unphased GWAS genotypes and receive phased and imputed genomes in return. Our server offers imputation from 1000 Genomes (Phase 1 and 3), CAAPA, HRC and the TOPMed reference panel. For all uploaded datasets an extensive QC is performed.
