Tag SNPs Functional Enrichment. Tag SNPs functional class enrichment before and after optimization. Each bin represents a single rank of functional class (most significant classes on the right). Only ranks with at least 100 tag SNPs prior to optimization are shown. Only tag SNPs meeting the minimum score requirements for inclusion in the panel are included in the histogram. Counts per bin are below each histogram bin and error bars at the top of bins are poisson estimates (the square root of the counts) scaled to percentage. Multiple functional classes match each rank, only one label shown for each rank.
