Distribution of TSD lengths and scores. Lengths of the 16,266 TSDs found by TSDfinder for L1s in the genome are shown as a histogram. The line indicates the average TSD score for each TSD length. The x axis displays the range of TSD lengths in nucleotides; the y axis displays the number of TSDs. The bimodal distribution suggests that a significant fraction of the 9-11-nucleotide TSDs may be artifactual.
