No. represents the quantity of tandem repeats in the ALL TRs set that were identified by RepeatMasker as having significant sequence identity with known repetitive elements. Occurrence/data set presents these data as the percentage of the sum of all such entries. Occurrence/genome reports the percentage of bases in the human genome sequence masked by each type of repetitive element.
