Fragment size discrepancy for map assembly of XhoI digest of E. coli K12 strain. For the restriction fragment sizes x of XhoI E. coli consensus map, y gives the true fragment sizes inferred from the published sequence; x − y gives the sizing error of consensus map fragments produced by our optical map assembler. (Left) The scatter plot shows the size discrepancy depending on the size of the underlying fragment. (Right) The histogram illustrates the marginal distribution of the size discrepancy for the finished restriction map.
