  1. Enrichment values of known ncRNAs in each filtering method or genome annotation. Column 2 contains the degree of enrichment of the known ncRNAs for each dataset compared to the "All" CRUFTS dataset. P-values for the enrichment were calculated using Fishers' exact test. In the final column, the ncRNA families contained within the annotation is indicated. See text for details and references.
