- 6. Bioinformatics|Software|Services A few of our NOVOALIGN users
- 8. Bioinformatics|Software|Services NOVOALIGN • Hash-based aligner • Peer reviewed publications: 2009-present • Accuracy – SNPs and short Indels • Read length > 250 bp as of V3.X.X
- 9. Bioinformatics|Software|Services ROC Curves • True Positive vs False positive rate • Higher Y value - better at finding the “true” result • Lower X value – better at excluding “false” results http://lh3lh3.users.sourceforge.net/alnROC.shtml

- 13. Bioinformatics|Software|Services “Our standard workflow uses novoalign based on its stringency in resolving large insertions and deletions. These results suggest equally good results using bwa mem, along with improved processing times” Courtesy Brad Chapman & Oliver Hoffman. HSPH http://bcbio.wordpress.com
- 14. Bioinformatics|Software|Services Graphical representation of the total number of downstream false positives expressed as a percentage... Oliver GR. 2012 [http://f1000r.es/NMpsFc] F1000Research 2012, 1:2 (doi: 10.12688/f1000research.1-2.v2)
- 15. Bioinformatics|Software|Services Novosort comparison on Illumina reads
- 17. Bioinformatics|Software|Services Motivation • Reach out to more users • Enable seamless integration with the cloud • Establish BaseSpace Novoalign community

Editor's Notes
- Figure 2. Graphical representation of the total number of downstream false positives expressed as a percentage of the true positive mutations detected following alignment with each aligner in single and paired-end mode across 67 groups of simulated Illumina reads.Each read group contained 20 SNPs and 13 INDELs.
