You probably need to glyph the output from the particle path and the streakline filter to see the locations. Right now I don't think any cells are being generated by those two filters. If you don't have any points, you'll probably need to set termination time to something other than 0 for particle paths. I haven't tested the streakline filter but suspect it has similar behavior.
