Hi Mohamad,<br>
<br>
I've been quietly following this thread in hopes that your interest
in particle tracing will spark a response from the developers. I was
unable to generate pathlines in image data in vti format I beleive I
was using 3.10.0 at the time. It was not clear to me if there was a
bug or if I had the pipeline built incorrectly out of my own
ignorance on how this works in PV. I posted a question with test
data hoping for some advise,

however I did not receive any reply.<br>

</div>
<div>2- Click on my data and create a "Temporal Cache" with
"Cache Size=2". </div>
<div><br>
</div>
<div>3- From "Sources", I create a "Line". </div>
<div><br>
</div>
<div>4- Click on TemporalCache1 and create a
ParticleTracer. </div>
<div> When the menu pops up, I choose </div>
<div> a) Input: TemporalCache1</div>
<div> b) Source: Line1</div>
<div>
Right after I click Ok, this is the message I get
(note that this message is shown even before giving me the
chance to change any flags on the "Properties" section
related to the "ParticleTracer1".</div>

<div>Luckily, Paraview does not crash and I can continue. </div>
<div>After doing some research, I am guessing that this has
something to do with the time conflicts (Pipeline fed into
the filter and the animation viewer time). </div>
<div><br>
</div>
<div><b>Observation:</b> Right after I create the
ParticleTracer and receive the error message, the time
shown in the animation viewer is increased from "0.0" to
"0.2". Why? </div>
<div><br>
</div>
<div>5- Recommended by the powerpoint, I set </div>
<div> a) Time Step: True (1) </div>
<div> b) Ignore Pipeline Time: True (1)</div>
<div><br>
</div>
<div><br>
</div>
<div>6- Now, I use "Animation View" as directed by the same
powerpoint to feed the time into the ParticleTracer1
filter. </div>
<div> a) Mode: Sequence</div>
<div> b) Create a keyframe for "ParticleTracer1".
Double click on the bar and set: </div>
<div>
<div> 1: time: 0.2, (interpolation
ramp), value: 1</div>
</div>
<div>
<div> 2: time: 1.8, (), value: 9 </div>
</div>
<div><br>
</div>
<div>Note: I have varied all the combinations listed above
to include/exclude the last/first steps. No luck! Nothing
really happening. </div>
<div> </div>
<div>7- Play animation. Result: nothing happening? What is
going on? </div>
<div><br>
</div>
<div><br>
</div>
<div><b>Observation: Using Paraview 3.8, I could see the
animation without adjusting any parameters in the
"Animation View" menu. Just the annoying error message
was shown. However, I could do the same thing with
Paraview 3.14, but it crashes after a few timesteps. </b></div>
<div><b><br>
</b></div>
<div>Anybody could share some hints on how to go about
this? </div>
