Gene-Level DRACH Motif Atlas of SARS-CoV-2 (2020 - 2025): N, Spike, ORF6, 5′ UTR, 3′ UTR
Description
This dataset contains per-genome DRACH motif annotations for 9,356,279 SARS-CoV-2 genomes across five genomic regions: 5′ UTR, Spike (S), ORF6, Nucleocapsid (N), and 3′ UTR. For each genome and region, it provides: seq_id: Genome identifier year: Collection year (2020–2025) drach_count: Number of DRACH motifs ([AGT][AG]AC[ACT]) drach_positions: 1-based genomic positions of motifs drach_sequences: Actual DRACH k-mers (e.g., GGACT) drach_density_per_kb: Motif count normalized per kilobase Data is derived from the Wuhan-Hu-1 reference (NC_045512.2) and processed from a globally representative aligned FASTA. Files are provided in tab-separated (TSV) format, with compressed .zst versions for efficient storage.
