Hi Piet!
Thanks for your answer. I haven't realised because I'm not still used to google groups discussions..
Finally, I decided to use the Pesca app in order to find the paths connecting one node to the rest of the network, and it is working quite well.
Giovanni, first of all I want to congratulate you for your job make in the app. It has been very helpful for me! The only thing that, in my opininon, is quite improvable is the "directed" check option.
For example: if I import in Cytoscape a network directly from Reactome (in BioPAX3 format), and then I use the Pesca app with "directed" option, the behaviour is not always the same. I mean that for edges types like "contains" or "member" it's difficult to follow the directions.
Anyway, thanks a lot for your job!
Best regards,
Miquel Oltra
