Different omics platforms—genomics, transcriptomics, proteomics, metabolomics and fluxomics—are generating new insights into how biological systems work at a molecular level. Although each individual omics approach provides a global view of a specific cellular process, this view is limited to only one aspect. In order to gain a comprehensive understanding of the system as a whole, researchers are faced with the challenge of merging these different types of results.
PathVisio is an open source tool for drawing and editing biological pathways and visualizing and analyzing data. In order to make multi omics data visualization more intuitive we developed new add ons for the software to enable visualization of multiple data sets that can be about data of different types. This also allows visualization of data on the lines that symbolize interactions and reactions in the pathways, essentially adding edge visualization for network biology. In this way we can for instance show results of fluxomics studies or from dynamic system biology models.
