DAN LAWSON BRC 2011 – ANNUAL MEETING UT SOUTHWESTERN MEDICAL CENTER DALLAS, TX SEPTEMBER 2011 Challenges and opportunities of new sequencing technologies
Challenges PATRICViPR/IRD EuPathDB VectorBase
Challenges & Opportunities of Next Gen Sequencing Sequencing reference assemblies re-sequencing isolates/strains RNA-Seq Metagenomics Population biology Data visualization Comparative genomics BRC focus Scalability Archiving data Assembly
Opportunities, Challenges, & Impact of Next Generation Sequencing Technologies: GSCID perspective Matthew Henn Director of Viral Genomics, Broad Institute Jennifer Wortman Director Microbial Informatics, Broad Institute Granger Sutton Professor Informatics, JCVI BRC Annual Mtng Session #2: GSCID Perspectives on Next Gen. Tech. Henn, Wortman, & Sutton
Large number of low cost Opportunity: large scale projects with comparative potential Challenges: Analyses computationally intensive Standardized analyses & reference selection Draft quality versus finished quality Genotype vs. phenotype correlations Visualization across large datasets & groups of samples Patient confidentiality Impacts: Pangenome construction Gene content/synteny analysis Phylogenetic reconstruction Time series analysis BRC Annual Mtng Session #2: GSCID Perspectives on Next Gen. Tech. Henn, Wortman, & Sutton
Opportunity: unprecedented sensitivity and specificity to detect sequence polymorphisms and genes Challenges: Integration of data from multiple technologies Read-based analysis Computationally & storage intensive need good read mapping to reference dbs Visualization (genome -> read) What data do you make available Levels of availability/access Data processing/QC steps Impacts: SNP calling Population Profiling (e.g. viral) Assembly & Haplotype Reconstruction Annotation BRC Annual Mtng Session #2: GSCID Perspectives on Next Gen. Tech. Henn, Wortman, & Sutton High Resolution Data from Multiple Platforms
Opportunity: Understanding community dynamics in health and disease, polymicrobial diseases Challenge: Exploratory (you don’t know what is there) What data are important & need be compared (e.g. reads, assemblies, variatns, genes, etc.) Read-based based analysis Metadata standardization Visualization Impacts: Sequence many organisms in parallel Profile community transcription Comprehensive identification of community members/functions BRC Annual Mtng Session #2: GSCID Perspectives on Next Gen. Tech. Henn, Wortman, & Sutton Microbial Community Profiling
