Reducing haystacks to needles - ViralClust: A Nextflow pipeline to cluster viral sequences.

ViralClust reduces viral genome datasets by approximately 95% while maintaining genetic diversity, enabling scalable analysis of large viral sequence collections.

• Why it matters: The rapid growth of viral genome data creates computational challenges and biases that hinder downstream analysis, emphasizing the need for effective data reduction strategies.
• What they did: ViralClust is a modular Nextflow pipeline that integrates five clustering algorithms to select representative viral genomes, evaluated on datasets up to 156,586 sequences.
• The result: The pipeline effectively minimizes dataset size while preserving diversity, facilitating efficient, reproducible analyses and allowing users to tailor clustering strategies to their specific research goals.
