Hi, The streakline filter requires a time dependent input as well as a vector field input (probably point data required but didn't verify this). After that, an input needs to be created for the seeds of the streaklines (i.e. the location that the streaklines go through). Select the time dependent input and then create the StreakLine filter. Then a dialog box will come up to set the seed source (Input should be set to the time dependent input and Seed Source should be set to the source to use for the streaklines). The seeds are the points in the Seed Source. Next, in the Properties panel you'll probably want to set Termination Time to something other than 0.0 since the streakline filter will integrate forward in time to that value. Thus, if it's 0.0 and the first time step is at 0.0 it will seem like the filter didnt' do anything. The Force Reinjection Every NSteps is essentially the resolution of the streakline.
Note that PV's implementation of streaklines only does forward integration in time.
