elDORS (v1) Database

Description

The elDORS (elevated Database Of RNA Sequences) database provides a massive-scale, updated repository of RNA sequence data curated from diverse genomic, non-coding RNA, and metagenomic sources. Following a rigorous hierarchical redundancy removal workflow, the dataset features two distinct tiers: the baseline elDORS_raw database (elDORS_raw_v1) containing 1.91 billion sequences, and a clustered and optimized elDORS version (elDORS_v1) containing 1.32 billion sequences (clustered at 80% sequence identity and 80% overlap, keeping sequences between 10 and 4096 nucleotides). To bypass severe network bottlenecks, the database is distributed in raw chunked formats, compressed archives, and pre-indexed pipeline builds optimized for immediate drop-in compatibility with deep RNA alignment tools like rMSA and the RNAcmap3-elDORS pipeline.

  • Description
    The complete elDORS v1 S3 bucket organized into four distinct database formats:
    1. Raw Sequence Distribution (/elDORS_v1_raw) - 1.2 TB baseline unclustered FASTA format sequence database.
    2. Compressed Archive (/GZIPPED_elDORS_v1) - elDORS (clustered at 80% identity, 80% sequence overlap, and filtering for length (10 to 4096), the optimized database contains 1.32 billion sequences (582 GB unzipped FASTA), 170 GB sequence-aware ~9GB chunks
    3. rMSA-Optimized Build (/rMSA_optimized_elDORS) - 1.0 TB uncompressed FASTA and BLAST format files optimized for using the database with rMSA ().
    4. RNAcmap3-Optimized Build (/RNAcmap3_optimized_elDORS) - 861 GB multi-volume BLAST and FASTA format files optimized for RNAcmap3-elDORS split-strategy pipeline.
