FastqCA: an effective FASTQ compressor through 2D spatial redundancy reduction.

FastqCA achieves competitive or superior compression ratios for FASTQ data by exploiting 2D spatial redundancy, maintaining genome assembly quality across key metrics.

• Why it matters: The explosion of high-throughput sequencing data creates urgent storage and transmission challenges, necessitating more efficient compression methods that do not compromise data integrity.
• What they did: FastqCA employs a reference-free, cellular automaton-based predictive algorithm to compress both nucleotide sequences and quality scores across reads and positions, tested against multiple existing tools on benchmark datasets.
• The result: The method delivers efficient compression while preserving assembly quality, enabling large-scale sequencing data archiving and transmission with minimal loss of critical information.
