This is the main project page for Edinburgh Pathway Editor (EPE). EPE is an extensible visual notation editing tool that is focused on Systems Biology applications.
The page primarily is concerned with EPE Version 3.0 which is a re-architected version of EPE 2.0 (available here ).
EPE 3.0 has support for SBGN  notations, including Process, Entity Relationship, and Activity Flow diagrams. In addition it supports a metabolic notation.
