Length distributions for different minimum threshold scores of TRF. a- Number of detections (log scale) with TRF in the human X chromosome as a function of length (in bp) for minimum threshold score between 20 and 50. The alignment weights were {2,7,7}, and the few detections larger than 200 bp were discarded. The solid vertical line represents the minimum length not affected by the threshold score constraint. b- Number of detections (log scale) with Sputnik in the human X chromosome as a function of length (in bp) for validation score set to 7, 8, 15, and 20. The mismatch penalty was -6, and the few detections larger than 200 bp were discarded.
