Functionalities

The ConsensusPathDB is accessible via a web interface providing a variety of functions.

Search and visualization

Using the web interface users can search for

Shortest path

Users can search for shortest paths of functional interactions between physical entities, based on all interactions in the database. The pathway search can be constrained by forbidding passing through certain physical entities.

Users can upload their own

Over-representation analysis

Using the web-interface of the database, one can perform overrepresentation analysis, based on biochemical pathways or on neighbourhood-based entity sets (NESTs) that constitute sub-networks of the overall interaction network containing all physical entities around a central one within a "radius" (number of interactions from the center). For each predefined set (pathway / NEST), a
