Thank you for reporting this issue!

Path4GMNS features a different design in synthesizing zones and demand compared to grid2demand. It does not have the concept of POI but rather activity nodes. Those nodes in Path4GMNS are randomly sampled for each zone according to a hardcoded sample rate r, which may lead to the reported issue that a zone does not have any nodes. Note that the zone is still there and is NOT MISSING. More details can be found here under Synthesize Zones and OD Demand.

Those non-activity nodes could be added to the corresponding zones. As they are useless in generating demand, we decide not to include them. If you think incorporation of them is critical, please open another ticket with justifications.

Path4GMNS uses this simple strategy to synthesize zones and demand to foster simple use. Users shall use grid2demand for more accurate zone and demand generation, e.g., if POI is present.
