Ogata, Jonathan D, Wancen Mu, Eric S Davis, Bingjie Xue, J Chuck Harrell, Nathan C Sheffield, Douglas H Phanstiel, Michael I Love, and Mikhail G Dozmorov. “Excluderanges: Exclusion Sets for T2T-CHM13, GRCm39, and Other Genome Assemblies.” Bioinformatics, April 3, 2023, PMID: 37067481, DOI: 10.1093/bioinformatics/btad198

Coordinates of problematic genomic regions that should be avoided when working with genomic data (Ogata et al. 2023). For human, mouse, and selected model organisms. Please, open an issue to suggest other resources. Package on Bioconductor: excluderanges.

New (2022-09-20) - Exclusion sets for human T2T-CHM13 and mouse GRCm39/mm39 genome assemblies are available. Download all data from Google Drive.

TL;DR - For human hg38 genome assembly, Anshul and we recommend ENCFF356LFX exclusion list regions. Also available as hg38.Kundaje.GRCh38_unified_Excludable excluderanges object (AnnotationHub ID: AH107305) and BEDbase.org.

BED files of exclusion regions are available on the ENCODE project website and scattered across various websites, such as Blacklist (Amemiya, Kundaje, and Boyle 2019), Peakpass (Wimberley and Heber 2019), Greenscreen (Klasfeld and Wagner 2022). Human and mouse genome assemblies have the largest number of exclusion sets generated by multiple labs. These exclusion sets frequently lack annotation and curation methods, creating uncertainty what to use. The purpose of this package is to provide a unified place for informed retrieval of exclusion regions.

Naming convention: <genome assembly>.<lab>.<original file name>, e.g., hg19.Birney.wgEncodeDacMapabilityConsensusExcludable.

See make-data.R how we created excluderanges objects.

Installation instructions

Install the latest release of R, then get the latest version of Bioconductor by starting R and entering the commands:

# if (!require("BiocManager", quietly = TRUE))
#     install.packages("BiocManager")
# BiocManager::install(version = "3.16")

Then, install additional packages using the following code:

# BiocManager::install("AnnotationHub", update = FALSE) 
# BiocManager::install("GenomicRanges", update = FALSE)
# BiocManager::install("plyranges", update = FALSE)

BEDbase data download

BEDbase.org is a repository for storing and analyzing BED files and BED sets, developed by Sheffield lab. It provides API for data access and retrieval.

Using BEDbase ID (e.g., 1a561729234c2844303a051b16f66656 for the hg38.Kundaje.GRCh38_unified_Excludable excluderanges object), we can construct a URL showing the splash screen with detailed information of the corresponding object, http://bedbase.org/#/bedsplash/1a561729234c2844303a051b16f66656.

We can also get the BED file using the BEDbase API.

wget http://bedbase.org/api/bed/1a561729234c2844303a051b16f66656/file/bed \
  -O hg38.Kundaje.GRCh38_unified_Excludable.bed.gz 

See also the R code to download T2T.excluderanges and mm39.excluderanges.

Mitochondrial DNA sequences, NUMTs

Mitochondrial DNA sequences (mtDNA, 100-600K mitochondria per human cell) transferred to the nucleus give rise to the so-called mitochondrial DNA sequences in the nuclear genome (NUMTs). In the settings of DNA/chromatin sequencing (e.g., ATAC-seq), we may observe up to 80% of mitochondrial sequencing reads that may pile up in the NUMT sequences. Similar to exclusion sets, genomic regions highly homologous to mtDNA can be masked to improve biological signal.

The reference human nuclear mitochondrial sequences have been available in the UCSC genome browser for hg19 and mm8 human/mouse genome assemblies. We collected NUMT sets for hg38, T2T-CHM13, mm10, generated by Caleb Lareau in the mitoblacklist GitHub repository. These NUMT sets can be combined with exclusion sets.

Centromeres, telomeres, etc.

Besides the ENCODE-produced excludable regions, we may want to exclude centromeres, telomeres, and other gap locations. The “Gap Locations” track for Homo Sapiens is available for the GRcH37/hg19 genome assembly as a UCSC ‘gap’ table. It can be retrieved from AnnotationHub, but lacks the metadata columns needed to decide the type of gaps.

# Search for the gap track
# ahData <- query(ah, c("gap", "Homo sapiens", "hg19"))
# ahData[ahData$title == "Gap"]
gaps <- ahData[["AH6444"]]

The UCSC ‘gap’ table provides better granularity about the types of gaps available. E.g., for human, hg19, we have the following types and the number of gaps.

Those objects are provided as individual GRanges.

Naming convention: <genome assembly>.UCSC.<gap type>, e.g., hg38.UCSC.gap_centromere. We can similarly load any gap type object.
