Abstract
BioNano Genomics has developed a method to fluorescently label long molecules of DNA, typically upwards of 100 kilobases, at nick sites generating a unique barcode pattern that can either be mapped to a reference or de novo assembled. In the present work, we demonstrate the ability to detect topological events in confined DNA from E. coli through identifying anomalous bright regions in the standard inter-calator YOYO signal along the length of the molecule. Topological events in DNA can mimic genomic structural variations by generating regions that appear as deletions or insertions to the reference resulting in false calls.
