2. Ecological genomics of the Northern krill: Genome assembly mask sequences

This file can be used to compute for example the number of accessible sites in windows of arbitrary lengths and correct diversity estimates. - genome_mask.gene_region_profile.fa.gz, a per-base file indicating genomic regions (e.g. intergenic, intron, CDS) computed from non-redundant protein-coding gene bodies (coordinates for those are given in a GFF file in another item) - genome_mask.gene_region_profile_masked_inaccessible.fa.gz, a per-base file indicating genomic regions as above, but inaccessible sites have been masked. - genome_mask.repeat_masked.fa.gz, a repeat-masked version of the genome assembly. - genome_mask.repeat_masked_rewritten.fa.gz, a repeat-masked version of the genome assembly, rewritten to encode repeated vs non-repeated bases differently. - 0 = inaccessible sites - 1 = accessible sites - 1 = intergenic - 2 = intron - 3 = 3′-UTR - 4 = exon (typically overwritten by UTRs or coding sequence) - 5 = 5′-UTR - 6 = CDS including any start and stop codons This item holds one major tar archive that contains three gzipped genome masks saved in FASTA format.

These files represents masks for the finished genome assembly of the Northern krill. In these files, sequence names are the same as those in the main genome assembly DNA file. Instead of containing DNA sequences however, the sequences contain per-base symbols indicating accessible sites or gene regions.
