Umap: Unique mappability of the genome

Description

These tracks indicate regions with uniquely mappable reads of particular lengths.

Umap single-read mappability

  • Umap S24: Uniquely mappable regions with a read length of 24 nucleotides
  • Umap S36: Uniquely mappable regions with a read length of 36 nucleotides
  • Umap S50: Uniquely mappable regions with a read length of 50 nucleotides
  • Umap S100: Uniquely mappable regions with a read length of 100 nucleotides

Umap multi-read mappability

  • Umap M24: Multi-read mappability with a read length of 24 nucleotides
  • Umap M36: Multi-read mappability with a read length of 36 nucleotides
  • Umap M50: Multi-read mappability with a read length of 50 nucleotides
  • Umap M100: Multi-read mappability with a read length of 100 nucleotides

You can use these tracks for many purposes including filtering unreliable signal from sequencing assays.

Umap single-read mappability tracks mark any region of the genome that is uniquely mappable by at least one k-mer. To calculate the single-read mappability, you must find the overlap of a given region with this track. Umap multi-read mappability tracks represent the probability that a randomly selected k-mer which overlaps with a given position is uniquely mappable.

For greater detail and explanatory diagrams, see the preprint, the Umap and Bismap project website , or the Umap and Bismap software documentation.

Track format

Single-read mappability tracks: bigBed 6-column format

Multi-read mappability tracks: bigWig

These tracks are available for m9/GRCm37, mm10/GRCm38, hg19/GRCh37 and hg38/GRCh38 genome assemblies.
