Facilitating analysis of genomic variation in Olympia oysters Bioinformatics, FISH546 Mackenzie Gavery 3/14/13
GOALS • Utilize existing genomic resources (transcriptome) for RAD-Seq design • Generate useful generic feature files (gff) to facilitate functional annotation of SNPs • Generate a workflow for annotating synonymous and non-synonymous SNPs in a non-model species*
Methods • Starting material: • Transcriptome: 41,000 contigs • SNP Table (CLCBio) ~52,000 • Annotations: blastx, GO • Tools: • Galaxy • Excel • Blastx
Results • New data tracks: • Gene ID • GO annotation sub-groups • SNPs • Blastxregions (with frame)
Applications • Assist with RAD-Seq experimental design • Ask interesting biological questions – are there differences in the number of SNPs in housekeeping v. inducible genes?
Next steps • Do these SNPs result in functional changes (i.e. do they change the protein)? • Blastxcustom output -outfmt “6 sseqid, qseqid, frames…” • aachanges (Galaxy)
