    Nucleotide sequence of the T2T-CHM13v2.0/hs1 genome assembly from UCSC

  description: |
    Nucleotide sequence of the T2T-CHM13v2.0/hs1 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` converts the downloaded `hs1.fa.gz` file from regular gzip compression to bgzip compression, then runs `samtools faidx` to create the required FASTA and bgzip index files. The original `hs1.fa.gz` file is removed, leaving only `hs1.fa.bgz`, `hs1.fa.bgz.fai`, and `hs1.fa.bgz.gzi` in the resource directory.
