Robinviz (Reliability Oriented Bioinformatic Networks Visualization) is a free Protein-Protein Interaction network visualization system. ****It is designed to visually aid the prediction and verification processes of such networks. Embedding both the reliability (confirmation) values associated with the interactions and the verification data pertaining to them within a visualization model is a novel feature of the system. RobinViz is a free, open-source software protected under GPL. It is written in C++ and Python, and consists of almost 30,000 lines of code, excluding the employed libraries.
