Keyword recovery scores as a function of combined intergenic distances between pairs of genes in a run. All gene members of a run (bordered on each side by genes in opposite orientations) were linked and given a value equal to the combined intergenic distances between them. While the keyword recovery of genes linked by a combined intergenic distance less than 150 bp is fairly high (34-52%), it is apparent that as the total intergenic distance increases above 150 bp, there is a decrease in keyword recovery. At combined intergenic distances above 250 bp the keyword recovery is comparable to that of randomly linked genes.
