PathwayArchitect systems biology-focused pathway analysis software offers a biology-focused workflow and a database of more than one million biological interactions. The package features a new method of exploring biological interactions, the Relevance Interaction Network. Relevance Interaction Network analysis begins with a protein list and identifies the network of proteins and small molecules which are most statistically related to the biology of the protein list. This algorithm makes it possible to easily identify binding complexes, transcriptional regulation networks, and even small molecules that regulate the biology of a group of proteins. The software supports MySQL and will shortly support Oracle databases. The software can be installed locally on the desktop or deployed as an enterprise-level solution, and is fully Mac, Windows, and Linux compatible. PathwayArchitect is fully integrated with Stratagene's ArrayAssist® suite of software for microarray data analysis. For advanced users, a new scripting engine is featured in all Stratagene software products that allow scripting of complex functions and user-defined workflows.
