PieceMaker: selection of DNA fragments for selector-guided multiplex amplification

We describe PieceMaker, a software tool for the design of applications of selector probes-oligonucleotide probes that direct circularization of target nucleic acid molecules. Such probes can be combined in parallel to circularize a selection of fragments from restriction digested total genomic DNA. These fragments can then be amplified in a single PCR using a common primer pair, yielding substrates for subsequent analyses, such as parallel genotyping or sequencing. However, designing multiplex selector assays is a laborious task. The PieceMaker program alleviates this problem by selecting restriction enzymes to generate suitable fragments for selection, and generating the output data required to design the selector probes.
