Description

Centromeric and Pericentromeric Satellite Annotation (cenSat)

Methods

Satellite array annotations are defined by intersecting information across alpha HOR annotation track, repeatmasker tracks, and human satellite annotation tracks. The broad definition of "peri/centromeric regions" on each chromosome includes the satellite-rich regions and 5 Mb of sequence on the p-arm and q-arm. Although the distal ends of acrocentric short arms are not truly pericentromeric, the vast majority of satellite DNAs present in these arms are highly enriched in peri/centromeric regions on other chromosomes (e.g. HSat1-3, Beta satellites (βSat), Alpha satellites (αSat)). Therefore, acrocentric short arms are included in the cenSat annotation track in their entirety. The Y chromosome peri/centromeric region includes 5 Mb to either side of the active αSat Higher Order Repeat (HOR) array, but we have included satellite array annotations across the entire chromosome. NB: Satellite array annotations typically merge across inserted transposons.

Strand information is not included (all annotations are set to + strand)
