Variant Detection with HiFi Reads - Understanding Results from the precisionFDA Truth Challenge
In this short video, Aaron Wenger, a Principal Scientist at PacBio, explains what highly accurate long reads, or HiFi reads, are and how they help to detect all variant types including single nucleotide, indels, and structural variants. He goes on to recap the precisionFDA Truth Challenge V2 which used Genome in a Bottle (GIAB) benchmarks to evaluate various sequencing technologies. In the 2020 challenge, when ranked for accuracy, PacBio HiFi reads delivered the highest precision and recall in all categories.
