GIGI

GIGI

A tool for rare variant genotype imputation. The GIGI algorithm can handle large pedigrees. Only a subset of individuals in a pedigree needs to be completely sequenced, GIGI will infer the missing genotypes at untyped markers, if the remaining individuals are sequenced solely at appropriate marker locations. GIGI-Quick can speed up the computation by running GIGI in parallel. See 'links'.
