In this PacBio User Group Meeting presentation, Tina Graves-Lindsay of the McDonnell Genome Institute and the Genome Reference Consortium speaks about the importance of phasing human reference genomes. Her team is now working on its fifteenth human genome assembly — part of a major effort to improve genomic representation of ethnic diversity — with a pipeline that generates 60-fold PacBio coverage for a de novo assembly, followed by scaffolding with other technologies. They are also using FALCON-Unzip to separate haplotypes, leading to reference-grade diploid assemblies. This approach has already helped resolve errors seen in other genomes and even the gold-standard…
In this PacBio User Group Meeting presentation, Jonas Korlach and Roberto Lleras share the latest updates to the structural variation application and analysis tools.
In this presentation Fritz Sedlazeck describes his latest work to obtain comprehensive genomes leveraging long-read sequencing and linked reads.
This webinar, presented by Nisha Pillai, provides an overview of amplicon sequencing to target specific regions of a genome using PacBio Single Molecule, Real-Time (SMRT) Sequencing. This session provides an overview of bioinformatics approaches for PacBio amplicon analysis including circular consensus sequencing and long amplicon analysis.
In this ASHG workshop presentation , Jonas Korlach, CSO of PacBio, walked attendees through recent product updates and the coming technology roadmap. The Sequel System 6.0 release offered major improvements to accuracy, throughput, structural variant calling, and large-insert libraries, he said, showing examples of 35 kb libraries. Looking ahead, Korlach said that the V2 express library preparation product should be available early in 2019, with the new 8M SMRT Cell being introduced sometime later.
In this ASHG workshop presentation, Elizabeth Tseng of PacBio showed how the Iso-Seq method can be used to discover disease-associated alternative splicing. Because this approach to isoform sequencing yields accurate, full-length transcripts requiring no assembly, it’s ideal for disease studies that need a more comprehensive picture of alternative splicing activity. Tseng offered several published examples of how the Iso-Seq method has been used for everything from single-gene studies to whole-transcriptome studies, and also detailed how the latest Sequel System chemistry recovers more genes and produces more usable reads.
PacBio Customers present their latest research in short talks at our User Group Meeting. The applications presented span the range of SMRT Sequencing applications from users from around North America.
In this webinar, Jonas Korlach, PacBio Chief Scientific Officer, and Dave Corney, Associate Principal Scientist, Next Generation Sequencing from GENEWIZ, describe the recent release of Sequel System 6.0, which has revolutionized long-read sequencing by providing users the ability to generate highly accurate single-molecule reads. Users no longer need to compromise read length for accuracy, because it is now possible to have both including Sanger-quality reads as long as 15 kb. They share the benefits in applications such as whole genome sequencing, structural variant detection, targeted sequencing and RNA sequencing of full-length transcripts using the Iso-Seq method. From those new to…
This tutorial provides an overview of the Structural Variant Calling application in SMRT Link and a live demo of how to launch an analysis in SMRT Link and interpret the results. This application identifies large (default: = 20 bp) insertions, deletions, inversions and translocations in a sample relative to a reference from.This tutorial covers features of SMRT Link v6.0.0.
This tutorial provides an overview of the Isoform Sequence (Iso-Seq) analysis application. The Iso-Seq application provides reads that span entire transcript isoforms, from the 5′ end to the 3′ poly A-tail. Generation of accurate, full-length transcript sequences greatly simplifies analysis by eliminating the need for transcript reconstruction to infer isoforms using error-prone assembly of short RNA-seq reads. This tutorial covers features of SMRT Link v6.0.0.
In this webinar, Lori Aro and Cheryl Heiner of PacBio describe how high-throughput amplicon sequencing using Single Molecule, Real-Time (SMRT) Sequencing and the Sequel System allows for the easy and cost-effective generation of high-fidelity, long reads from amplicons ranging in size from several hundred base pairs to 20 kb. Topics covered include the latest advances in SMRT Sequencing performance for detection of all variant types even in difficult to sequence regions of the genome, multiplexing options to increase throughput and improve efficiency, and examples of amplicon sequencing of clinically relevant targets.
In this AGBT presentation, Marty Badgett shares a look at the latest results from circular consensus sequencing (CCS) mode for highly accurate reads and data from our soon-to-be-released Sequel II System. As he demonstrates, CCS reads cover the same molecule many times, delivering high consensus accuracy despite noisy raw reads; on average, reaching 10 passes achieves Q30 accuracy. Badgett offers several examples where this is useful, such as pharmacogenomic gene analysis and resolving metagenomic communities. He also provides an update on the Iso-Seq method, which can now segregate transcripts into haplotype-specific alleles using a new tool called Iso-Phase.
In this ASHG workshop presentation, Janet Song of Stanford School of Medicine shared research on resolving a tandem repeat array implicated in bipolar disorder and schizophrenia. These psychiatric diseases share a number of genomic risk variants, she noted, but scientists continue to search for a specific causal variant in the CACNA1C gene suggested by previous genome-wide association studies. SMRT Sequencing of this region in 16 individuals identified a series of 30-mer repeats, containing a total of about 50 variants. Analysis showed that 10 variants were linked to protective or risk haplotypes. Song aims to study the function of these variants…
In this AGBT presentation, Mike Hunkapiller shares insights on using highly accurate long (HiFi) reads generated in circular consensus sequencing (CCS) mode for comprehensive genomic analysis and provides examples such as the sequencing of a Genome in a Bottle reference sample, which concluded with Q48 accuracy, 18 Mb contigs, and clearly phased haplotypes.
