Hello again Jakob, sorry to bother you again.
I'm still trying to launch the tool implausibleRoutes.py but it still
raises the same error. I thought the problem could be in my network large
extent (I need to simulate a middle-sized european city) so I clipped it to
a lower extent, but the problem persists.
After running flowrouter.py, I launch implausibleRoutes.py and this is what
I get:
Loading net ... done.
*Error: No route input specified or all routes were invalid.*Quitting (on
error).
parsing network from sumonetwork_zgzfixed.net.xml

It seems that implausibleRoutes.py cannot read the routes from routes.xml,
but not sure why. The routes.xml contains routes of this form:
<route id="678695567_678859243.qPKW.1380" edges="678695567 80784908
136656809 92741288#1 124019581#0 124019581#2 678859243"/>
Kind regards,
Alejandro
