Genotype-to-phenotype maps and the related fitness landscapes that include epistatic interactions are difficult to measure because of their high dimensional structure. Here we construct such a map using the recently collected corpora of high-throughput sequence data from the 75 base pairs long mutagenized E. coli lac promoter region. where each sequence is associated with its phenotype. https://www.missouriquiltcoes.shop/product-category/10-squares-layer-cakes/
