With the development of new high-information content fingerprinting techniques for constructing BAC-based physical maps, physical map construction is accelerating and it is important to determine which methodologies work best. In a recent publication (Z. Xu et al., 2004, Genomics 84:941-951), Xu et al. evaluated five different techniques (one agarose-based and four using multiple enzymes) and concluded that a two-enzyme technique was superior. In addition, they found that no benefit was gained from fingerprinting more than 10× coverage. In this paper we report our own extensive simulation results, which lead to contrasting conclusions. Our data indicate that the five-enzyme method known as SNaPshot is the most effective and that the assembly can in fact be significantly improved with greater than 10× coverage.
