NCBI-NIAID Beyond Phylogenies Codeathon was a success!

SARS-CoV-2 genomic data is critical for monitoring the viral spread and evolution of the COVID-19 pandemic, identifying newly emerging variants, and developing and evaluating the countermeasures. As of September 2022, over 13 million SARS-CoV-2 genomes have been sequenced across the world, making it the most sequenced pathogen ever. A cornerstone of genomic analysis is building … Continue reading NCBI-NIAID Beyond Phylogenies Codeathon was a success!
