Cluster intervals

Interpretation: a sourced cluster interval comes from a named database or publication. Its sourced-interval coverage is shown as 100% because the row is the sourced interval itself. For a PICB-detected interval, Source database / sequencing dataset identifies the reads used for detection, Detection tool names PICB and its version, and Source or method reference labels the PICB method paper explicitly. Contained accepted piRNA sequences counts distinct accepted piRNA sequences whose accepted genomic loci are fully inside the interval. Sourced-interval coverage is the union of coordinate intersections with sourced intervals divided by the PICB interval length; strand is not used. The website displays only PICB-detected intervals with accepted-piRNA-locus enrichment FDR ≤0.05 after 1,000 matched random placements. Reads were not permuted and PICB was not rerun, so this is a post-PICB website display threshold rather than PICB's caller-level FDR. PICB intervals above the threshold remain in the downloadable SQLite database.
