GO annotation annotation Up to October 26, 2010, there have been more than 2,753,338 annotations covering 48 species in GO database • Background
Enrichment analysis • Background
Workflow • Visualization • + • Analysis • Including as more as possible functions of other software • Relatively independent modules with interactions • Very flexible, 4 individual plugins or 1 bundle • Background
Batch Mode • More than 150 plugins . • Background
Visualization (Mosaic) • Partitioning with BP • Layout with CC • Coloring with MF • Automatic annotation • ID mapping • Overview network . • Mosaic
1st Partitioning/decomposition • Decompose a huge biological network to sub-networks (Biological process) • Mosaic
2nd Layout/Pathway • Currently only support PathVisio and WikiPathway formats (Cellular components) • Mosaic
3rd Coloring/Highlighting • Molecular function • Other projects>AVALON
3rd Coloring/Highlighting • Molecular function • Other projects>AVALON
Overview network • Mosaic
Analysis (NOA) • Edge-base algorithm • Batch mode • Heatmap • Overview network • Interaction with Mosaic • NOA
Batch mode • NOA
Example 400 Human Pathways • NOA
Novel algorithms development • Meta-analysis and multiply network integration • Functional module detection and decomposition Future Works
Current plugin improvement • Extending CyThesaurus • OBO/pathway file parsing • Functional annotation • Database file management • Future Works
Customized pipeline Future Works
