Manipulation and filtering of GTAN to gain insights of gene-gene relationships. The GTAN from Fig. 12 was merged into a gene-gene network through shared terms: if two genes share a common term, then draw a line in between these two genes and get rid of the term and its original association lines, and then the graph was rebuilt by SVG (see Additional file 14). Before merging, some generic GO terms (high rank in GO hierarchy, e.g. physiological process) were eliminated for simplicity purpose. Genes are selected by highlighting in red for further manipulation (see Additional file 14). Then the obtained PSCP file containing the merged network was colored by the CRI files from the time course experiments (same CRI files as in Fig. 5).
