The Opportunity
•NGS instruments have recently given us the ability to characterize the microbiomes that we live in and that live in us.
•We can get a step closer to this goal by creating a visualization program that facilitates manual data curation by a human.

Your Mission
Invent novel visualization approaches to represent metagenomic data.
Subgoals:•Pick out anomalies within a given dataset. •Generate time series representation of multiple datasets.•Compress data efficiently to allow visualization of huge datasets.

Metagenomic datasets (FASTQ format) from clinical and environmental samples.
• Metagenome of the human oral cavity under healthy and diseased conditions, with a focus on supragingival dental plaque and cavities. – “oral_healthy” and “oral_diseased” datasets– Roche 454
• Nose/throat swab from Nicaraguan child with acute respiratory illness– “nicaragua” dataset– Illumina
The Data (I)

• Skin surface from the palm of a human hand – “palm” dataset– Roche 454
• Human abscess sample of unknown etiology – “abscess” dataset– Illumina

• KRONA allows hierarchal data to be explored with zoomable pie-charts. – Excel template or KRONA tools. – Support for several bioinformatics tools and raw data formats.
