Hello,  
I have created stream lines in my simulation using streamTracerWithCustomSource. and using the points of the inlet patch of my mesh as origin of the streams. this works great. what I am looking to do now, is sample along each stream line separatly. something similar to doing a polyline (PolyLineSource) and resample over it (ResampleWithDataset) but instead of doing a polyline use each stream line separatly. how can I achieve this? i wanted to use conectivity filter over the streamTracerWithCustomSource filter but it is not available.  
thanks in advance,

Okey, I solved by using threshold with seedIDs
