[i] Sequences were partitioned over an arbitrarily defined tissue hierarchy designed to group physically related tissues and remain within constraints of computational resources. Genomic tissue is a set of ESTs labeled only as having a genomic region of hybridization without a tissue source. The set of duplicate copies of all disease-related sequences is loosely referred to as a tissue for this work.
