Our laboratory has developed a new physical approach to genomic analysis named Optical Mapping, which uses modified surfaces to fix DNA molecules for biochemical modification. Restriction enzymes are used to cleave fixed molecules, and after staining with a non-specific fluorochrome, DNA fragments are analyzed under a microscope to produce high resolution, ordered restriction maps. The use of sophisticated machine vision techniques and Bayesian modeling approaches enables fully automatic construction using an assortment of cloning systems. Throughput is further enhanced by using large a number of samples arrayed by a robotic system on Optical Mapping surfaces, and successful implementation of a fully integrated automated image collection/analysis system, featuring specialized file management and distributive processing.
