Locus Identification Using a Gene Interval Graph. Red and blue nodes in this interval graph correspond to reference and prediction gene annotations (respectively) as shown in Figure Figure1.1. Two nodes are connected by an edge if the corresponding gene annotations overlap. Each connected component in the graph represents a distinct gene locus, defined as the smallest genomic region containing every gene annotation associated with the corresponding subgraph. In this example, nodes representing five reference annotations and four prediction annotations are shown. The four connected components in the graph correspond to four gene loci, for which precise genomic coordinates can be determined from the associated genes (shown in orange brackets in Figure Figure11)
