4 4 Sample Prep Sequencing Analysis Integration Streamlined end-to-end solution Industry’s leading NGS instruments Storage, Processing, Analysis & Collaboration Suite of DNA, RNA & Targeted Solutions

5 5 Assessing seasonal blooms of Cyanobacteria (blue-green algae) in drinking water that can impact water quality. Collaboration with Center for Earth and Environmental Science, IUPUI 49 reservoir samples collected in different months, at discrete depths. Study combines 16S analysis on MiSeq with shotgun metagenomics on NextSeq Case study: Eagle Creek reservoir, Indiana By courtesy of: Nicolas Clercin (IUPUI), Rob Schmeider, Brian Steffy, Clotilde Teiling, Kameran Wong (Illumina)

7 7 Workflow overview 16S rRNA Sequencing was done on 27 of the samples Primer pair sequences for V3 and V4 region create a simple 460 bp long amplicon. Nextera XT indexing kit for 96 samples in parallel 100,000 reads per sample if using all 96 indexes. Comparative genomics Phylogenetic classification Genomic DNA extraction Sample Prep V3–V4 region Amplification Library Prep MiSeq & Primary Analysis Secondary Analysis The Meta-G-Nome™ DNA Isolation Kit is used to isolate inhibitor-free, fosmid cloning-ready DNA from unculturable or difficult-to-culture microbial species present in environmental water, soil, or compost samples.

8 8 16S metagenomics on BaseSpace

9 9 Can run on-instrument using MiSeq Reporter or in cloud with BaseSpace Both analysis pipelines use the same classification algorithm and taxonomic database. –The classification algorithm is a high performance implementation of the published RDP Naïve Bayesian Classifier (http://dx.doi.org/ %2FAEM )http://dx.doi.org/ %2FAEM –The database is an Illumina-curated version of the GreenGenes Consortium 16S rRNA database. Redundant sequences and entries with missing or partial labels are removed. Provides fast, high-accuracy species-level taxonomic classifications Uses full length of Illumina paired-end reads Outputs: PDF reports, raw data (CSV), interactive visualizations Taxonomic classification

12 12 Sample Extraction Library Prep NextSeq Sequencing Analysis Shotgun metagenomics on NextSeq: workflow overview 11 samples sequenced in 1 NextSeq run 400 million 2×150bp read pairs generated in 29 hours 78.8% of bases exceeded Q30 Analysis done with MG-RAST

13 13 Seasonal variation in composition at bottom of lake 25 th July Actinobacteria 33% 23 rd May Actinobacteria = 76% 23 rd October Actinobacteria=79% Ongoing challenge: what should be our data analysis pipeline for shotgun metagenomic data, e.g. on BaseSpace? Several standalone apps for taxonomic classification Seem to be fewer options for functional classification

14 14 HiSeq 1 terabase run (R&D data) Per run you can do up to: −10 genomes −150 exomes −80 WT RNA samples *Assumes 100Gb, 30x genome; Nextera Rapid Capture Exome; 50M reads per RNA sample 2 x 125 Cycles

15 15 Challenge: efficient storage and access for shotgun metagenomic data Resequencing data (Human genome build ~160 Gbp, ~400 Gbyte FASTQ) FASTQ (gzipped) 150 Gbyte BAM (40 Q-scores) 120 Gbyte BAM (8 Q-scores) 82 Gbyte BAM (consensus compressed) 60 Gbyte CRAM (consensus compressed) 27 Gbyte Relies heavily on known high-quality reference sequence Resequencing data (Human genome build 145Gbp, ~160 Gbp, ~400 Gbyte FASTQ) FASTQ (gzipped, 8 Q-scores) 89 Gbyte BWT compression (now) 37Gbyte BWT compression (likely achievable) 23 Gbyte 89  37Gbyte: BWT/PPM for reads, simple binning of Q-scores (lossless) Sort reads for better compression – save 4Gbyte (Cox et al., 2012) Discard uninformative Q-scores (reference free) – save 10Gbyte (Janin et al., 2012)

16 16 Trading compression for searchability Resequencing data (Human genome build ~165 Gbp) FASTQ (gzipped) 152 Gbyte BWT (searchable) 105 Gbyte NB: 40 Q-scores, both FASTQ and BWT would be smaller for 8 Q-scores For a query sequence q, returns: Full FASTQ record (sequence, Q-scores, read names) for all reads containing q … and full FASTQ record of their read pairs Pipe search output directly to your favourite tool, e.g. Velvet Applications: “In silico pull-down” Assembling breakpoints Genotyping complex variants by tracking k-mers Reads (BWT) :26 Gbyte Q-scores (razip):64 Gbyte Read names (razip):15 Gbyte Further info: beetl.github.io/BEETL/, Janin et al.
