My new tool Paraviewer is now available for use at github.com/PacificBiosc...! If you use Paraphase, try this new next-step tool - it automates and greatly simplifies variant visualization from Paraphase variant calling. If you're at #ASHG2025, visit me today at poster 4109W. #pacbio

My complex variant visualization tool SVTopo is now officially published in BMC Genomics! link.springer.com/article/10.1.... This tool allows HiFi users to view complex germline structural variation in intuitive and informative plots.

Complex structural variant visualization with SVTopo - BMC Genomics
Background Structural variants are genomic variants that impact at least 50 nucleotides. Structural variants can play major roles in diversity and human health. Many structural variants are difficult to interpret and understand with existing visualization tools, especially when comprised of inverted sequences or multiple breakend pairs. Results We present SVTopo, a tool to visualize germline structural variants with supporting evidence from high-accuracy long reads in easily understood figures. We include examples of 101 visually complex structural variants from seven unrelated human genomes, manually assigned to ten categories. These demonstrate a broad spectrum of rearrangement and showcase the frequency of complex structural variants in human genomes. Conclusions SVTopo shows breakpoint evidence in ways that aid reasoning about the impact of multi-breakpoint rearrangements. The images created aid human reasoning about the result of structural variation on gene and regulatory regions.

I just released a new preprint! The manuscript describes SVTopo, a software tool that enhances visualization of complex SVs using HiFi data: www.biorxiv.org/content/10.1.... Here’s a summary of the results:

Great to see that sawfish, our new HiFi SV caller, is accepted for publication in Bioinformatics! Sawfish emphasizes local haplotype modeling to improve SV representation and genotyping in both single and joint-sample analysis. Advance-access article now available: (1/n) doi.org/10.1093/bioi...

Another very insightful paper on #methylation and long-read sequencing by @gangfang.bsky.social, describing some important but frequently overlooked caveats. Gang provides a fantastic summary in his post, but here's my take too😅:

#ASHG2024 was a blast. I had great discussions with friends and #pacbio collaborators, presented a poster on my new tool SVTopo, welcomed #PacBioVega to the world, and realized than I'm a bigger fan of One Republic than I knew before. Excited for next time!
