It's official, @PacBio has launched a new benchtop sequencer! Quick summary of the new Vega system: - instrument = $169k - consumables = $1100 per run - output = 60 Gbp, 24 hr run time This is the #HiFi sequencer #microbiology labs have been asking for. pacb.com/press_releases…

Today, we announced the first #PacBio benchtop long-read sequencing system, Vega. #Vega delivers all the functionality of #Revio into a compact, lower- throughput benchtop platform. bit.ly/3O0mP5b #ASHG24 #ASHG2024

I'm happy to announce that SVTopo, a new computational tool from PacBio (github.com/PacificBioscie…), is ready for you to try. SVTopo creates simple images so you can rapidly understand complex changes in genome structure. See me and learn more at ASHG 2024 in Denver, poster 1180W

We've been making steady usability updates to the sawfish SV caller thanks to user feedback, including a new feature to output all supporting reads for each SV. The latest binary, user guide, and (new) source code release are available on github here: github.com/PacificBioscie…
Chris Saunders@ctsa11

We assessed our new method on the recent draft GIAB SV benchmark from the T2T-HG002-Q100 assembly, finding sawfish has the highest F1-score among evaluated callers on every tested SV size range and depth level. Other callers required at least 30x depth to reach sawfish at 15x:

Very excited to share our work on building a benchmark of all classes of variation based on the large CEPH-1463 pedigree sequenced with all the technologies. A large team effort! biorxiv.org/content/10.110…

I am going on the faculty job market this year, so if your home department is starting a search, I'd love to hear about it. Thanks!

Don't miss out on this #metagenomics webinar next week! @PacBio HiFi sequencing on Revio can be used to generate single-contig, complete MAGs from the most difficult sample type to assemble - soil. Results for wetland and grassland soil shown here, from my talk at LAMG.

I'm happy to see sawfish now available for the community to use. Sawfish is another step towards high accuracy and consistent SV genotyping. Great work by Chris Saunders and many others.

Finally, thanks to our early users for their helpful feedback, and to the GIAB/T2T community for ongoing development of new SV benchmarks and assessment methods, which will continue to be crucial to further improvement efforts.
