Distribution (top) and cumulative distribution (bottom) of the number of 1000 Genomes Phase 3 haplotypes consistent with short paths in the GRCh37 chromosome 22 graph. Primary mappings of 101 bp reads with scores of 90 out of 101 or above (\(n=1,500,271\)) are the solid blue line. Secondary mappings meeting the same score criteria (\(n=43,791\)) are the dashed green line. Simulated 100 bp random walks in the graph without consecutive N characters (\(n=686,590\)) are the dotted red line. Consistent haplotypes were counted using the gPBWT support added to vg .
