I haven't been able to find the following in the documentation at http://www.repeatmasker.org/
(1) Why are certain regions classified as "Other"? Are these regions impossible to concretely classify due to alignment issues?
(2) I believe that centromeric and telomeric regions would be classified as tandem repeats. Are telomeric/centromeric regions classified as "DNA" within the hg19 version of RepeatMasker?
Are these documented somewhere?
