    Nucleotide sequence of the T2T-CHM13v2.0 genome assembly

  description: |
    Nucleotide sequence of the T2T-CHM13v2.0 genome assembly, providing gapless reference chromosomes from telomere to telomere, including complete centromeres and rDNA arrays, based on a female (46,XX) haploid-derived cell line and therefore lacking the Y chromosome.

    Processing Details: 

    build.sh unzips the original file, replaces chromosome names with ucsc naming (e.g. chr1), rearranges chromosomes by conventional order (chr1, chr2,...) and creates an index file using 'samtools faidx'.
