This webinar, presented by Roberto Lleras, provides the best practices for working with PacBio tools (SMRT Link and Developmental) on the command line. Please access this file for step-by-step instructions for installing SMRT Analysis tools and pbbioconda in order to analyze SMRT Sequencing data on the command line: https://www.pacb.com/wp-content/uploads/Bioinformatics-Webinar-Session-1-Getting-Started.pdf
With the Sequel II System powered by Single Molecule, Real-Time (SMRT) Sequencing technology and SMRT Link v7.0, you can affordably and effectively detect structural variants (SVs), copy number variants, and large indels ranging in size from tens to thousands of base pairs. PacBio long-read whole genome sequencing comprehensively resolves variants in an individual with high precision and recall. For population genetics and pedigree studies, joint calling powers rapid discovery of common variants within a sample cohort.
With highly accurate long reads (HiFi reads) from the Sequel II System, powered by Single Molecule, Real-Time (SMRT) Sequencing technology, you can comprehensively detect variants in a human genome. HiFi reads provide high precision and recall for single nucleotide variants (SNVs), indels, structural variants (SVs), and copy number variants (CNVs), including in difficult-to-map repetitive regions.
In this presentation, Elizabeth Tseng explains how PacBio's full-length RNA Sequencing using the Iso-Seq method can characterize full-length transcripts without the need for computational transcript assembly. The Iso-Seq method is fully supported bioinformatically through PacBio's SMRT Analysis software that outputs high-quality, full-length transcript sequences that can be used for genome annotation and novel gene discovery. Elizabeth shows that the highly accurate reads can be used to discover allelic-specific isoform expressions in transcriptome data.
The PacBio Iso-Seq method produces high-quality, full-length transcripts of up to 10 kb and longer and has been used to annotate many important plant and animal genomes. Here we describe an improved, simplified library workflow and analysis pipeline that reduces library preparation time, RNA input, and cost. The Iso-Seq V2 Express workflow is a one day protocol that requires only ~300 ng of total RNA input while also reducing the number of reverse transcription and amplification steps down to single reactions. Compared with the previous workflow, the Iso-Seq V2 Express workflow increases the percentage of full-length (FL) reads while achieving…
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.
Although the accuracy of the human reference genome is critical for basic and clinical research, structural variants (SVs) have been difficult to assess because data capable of resolving them have been limited. To address potential bias, we sequenced a diversity panel of nine human genomes to high depth using long-read, single-molecule, real-time sequencing data. Systematically identifying and merging SVs =50 bp in length for these nine and one public genome yielded 83,909 sequence-resolved insertions, deletions, and inversions. Among these, 2,839 (2.0 Mbp) are shared among all discovery genomes with an additional 13,349 (6.9 Mbp) present in the majority of humans,…
The PacBio Platform includes an extensive software portfolio that employs key advantages of SMRT (Single Molecule, Real-Time) Sequencing technology: extraordinarily long reads, highest consensus accuracy, uniform coverage and simultaneous epigenetic characterization. Core elements of our analytical portfolio include SMRT Analysis software, DevNet and SMRT Compatible products.
