PacBio scientists Kristi Kim and Michael Weiand present on high-throughput solutions for sample preparation including 10 kb template preparation, high-throughput PacBio RS II sample prep kits, and compatible automated liquid handling platforms.
This seminar features great hands-on information and best practices for analyzing SMRT Sequencing data for eukaryotic genome assembly. Michael Schatz provides an overview of the assembly tools, provides recommendations for when to use each one, and discusses the challenges of short-read assemblies. James Gurtowski gives an in-depth overview of hybrid assemblies methods, where short read data are used used to correct errors in longer reads. Finally, Sergey Koren presents on chromosome-scale assembly, including the MinHash Alignment Process (MHAP) he developed to dramatically reduce the computational processing power required for genome assemblies.
Jonas Korlach, CSO of PacBio, discusses the scientific value of >10 kb, unbiased sequencing reads for an expanding range of applications. Single molecule, real-time (SMRT) Sequencing technology has rapidly advanced in read lengths, throughput and adoption in the past year – a review of published work from a variety of researchers utilizing these new capabilities is also conducted.
In this BioConference Live webinar, PacBio CSO Jonas Korlach highlights how multi-kilobase reads from SMRT Sequencing can resolve many of the previously considered 'difficult-to-sequence' genomic regions. The long reads also allow phasing of the sequence information along the maternal and paternal alleles, demonstrated by full-length, fully phased HLA class I & II gene sequencing. In addition, characterizing the complex landscape of alternative gene products is currently very difficult with short-read sequencing technologies, and he describes how long-read, full-length mRNA sequencing can be used to describe the diversity of transcript isoforms, with no assembly required. Lastly, in the exciting area of…
PacBio CSO Jonas Korlach describes the Iso-Seq method for full-length transcript isoform characterization using SMRT Sequencing. He presents published research using the method for full isoform characterization, including papers from Stanford scientists who analyzed full transcriptomes with SMRT Sequencing. With the Iso-Seq method, researchers found novel isoforms and novel genes even in well-studied cell lines.
Lizzie Wilbanks formerly from UC Davis, discusses how longs read from SMRT Sequencing allow accurate assembly of members from the complex pink berry salt marsh community.
In this webinar, Elizabeth Tseng from PacBio demonstrates how to run the Iso-Seq bioinformatics software pipeline that is part of PacBio's SMRTAnalysis software suite. Both the web portal interface (SMRT Portal) and the command line version will be introduced. In addition, she reviews the community version of Iso-Seq (pbtranscript-tofu) and other community tools to perform additional analyses.
In this webinar, Tyson Clark from PacBio discusses the recent Iso-Seq template preparation protocol updates for creating full-length cDNAs and discusses considerations for experimental design.
Dr. Olga Vinnere Pettersson, Uppsala Genome Center (Uppsala University), presents best practices for qualifying genomic DNA from a variety of sources to be suitable for Single Molecule, Real-Time Sequencing. Factors that affect single molecule sequencing and recommendations for extracting high-quality genomic DNA will be described. (requires file download to view)
Neema Mayor from Anthony Nolan Research Institute offers an introduction to the challenges of characterizing the HLA region, noting that improvements in resolution have allowed scientists to dramatically expand the number of classifications used to match donors to recipients. As sequencing resolution improves, Mayor says, scientists expect to find even more polymorphisms than what has been already catalogued.
In this webinar, the presenters describe a targeted sequencing workflow that combines Roche NimbleGen's SeqCap EZ enrichment technology with PacBio' SMRT Sequencing to provide a more comprehensive view of variants and haplotype information over multi-kilobase, contiguous regions. They demonstrate that 6 kb fragments can also be utilized to enrich for long fragments that extend beyond the targeted capture site and well into (and often across) the adjacent intronic regions. When combined with SMRT Sequencing, multi-kilobase genomic regions can be phased and variants, including complex structural variants, can be detected in exons, introns and intergenic regions.
Brett Hannigan, Computational Biology Project Leader at DNAnexus, demonstrates a fast, accurate, and cost-efficient solution for diploid-aware de novo genome assembly utilizing FALCON on the DNAnexus platform.
Andrew Carroll, Director of Science at DNAnexus, presents how to greatly improve the accuracy of SV-calling by using long-read PacBio sequencing and fast and easy-to-run cloud-optimized apps like PBHoney, Parliament, and Sniffles.
PacBio Sequencing is characterized by very long sequence reads (averaging > 10,000 bases), lack of GC-bias, and high consensus accuracy. These features have allowed the method to provide a new gold standard in de novo genome assemblies, producing highly contiguous (contig N50 > 1 Mb) and accurate (> QV 50) genome assemblies. We will briefly describe the technology and then highlight the full workflow, from sample preparation through sequencing to data analysis, on examples of insect genome assemblies, and illustrate the difference these high-quality genomes represent with regard to biological insights, compared to fragmented draft assemblies generated by short-read sequencing.
