What is the relation between PathVisio and GenMAPP?
PathVisio has grown out of a need to extend GenMAPP. GenMAPP has many good features but has hit limits in terms of its flexibility to adapt to new needs. We cooperate closely with the GenMAPP group to share code and ideas. PathVisio borrows heavily from the good aspects of GenMAPP, such as its simplicity and usability, but tries to improve on other aspects, such as flexibility and expansion to other platforms (linux and Mac OS X).
