GO annotation

Background

Up to October 26, 2010, there have been more than 2,753,338 annotations covering 48 species in GO database

Workflow

Background

Visualization+

Analysis

•Including as more as possible functions of other software

•Relatively independent modules with interactions

•Very flexible, 4 individual plugins or 1 bundle

6

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

9

1st Partitioning/decomposition

• Decompose a huge biological network to sub-networks (Biological process)

Mosaic

10

2nd Layout/Pathway

• Currently only support PathVisio and WikiPathway formats (Cellular components)

Mosaic

11

3rd Coloring/Highlighting

• Molecular function
