From Metagenomic Sample to Useful Visual Anna Shcherbina 01/10/ 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.

From Metagenomic Sample to Useful Visual Anna Shcherbina 01/10/ 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.

From Metagenomic Sample to Useful Visual Anna Shcherbina 01/10/ MEGAN4-MEtaGenomoe ANalyzer A simple lowest common ancestor algorithm assigns reads to taxa. Taxonomic level reflects the degree of conservation of a sequence. Dissects large datasets without assembly or the targeting of specific phylogenetic markers. Graphical and statistical output for comparing different datasets.
