CalicoST phases input alleles in Y 0 and D 0 using a database of haplotypes. Optionally, CalicoST infers tumor proportion per spot using the BAF. CalicoST jointly models transcript counts and allele counts as functions of allele-specific copy number states within each clone. CalicoST uses an HMM to model correlations between copy number states from adjacent genomic regions and a HMRF to model correlations between the cancer clones assigned to neighboring spatial locations.
