- SkewDB is a free database containing GC and other skew data for over 53,000 chromosomes and plasmids, last updated on July 5, 2024, now including homopolymer counts and codon bias data.
- The database is created using open-source Antonie software, based on public DNA sequence, annotation, and taxonomic data from NCBI, and provides individual files with 4096-nucleotide granularity for each chromosome.
- Key features include fields for skew gradients (e.g., GC, TA, strand bias), codon position analysis, taxonomic classification, and fit quality metrics, with the project aiming to support research on GC skew and chromosome behavior.
