I don't really know what to say. I tried myself using our installed
version of ParaView 3.4 (linux) to<br>
1) load a time dependent dataset<br>
2) Add a temporal cache<br>
3) Create a line source<br>
4) Instantiate the ParticleTracer (don't use the Pathline filter - that
is used to generate trails from particles that you create with the
particle tracer).<br>
<br>
I got the input selection dialog box and all seemed normal.<br>
<br>
I do not use a Mac so I just don't know what could be wrong, but it
seems unlikely that the mac version could work normally the rest of the
time and only have this one dialog missing.<br>
<br>
Can you try another machine/platform.<br>

<pre wrap="">Hi again,
thank you for fast answer John! I'm aware of the problem that my particle
tracer doesnt have any seed source, but I have been working for quite
awhile sloving this problem. I did as you said, created temporalcache and
seed (point seed) but I cant connect the 2 with my particle tracer. I
found your (John's) great powerpoint presentation on the web explaining
everything there is to explain. Though I cant make it work!!! In one of
the pictures in the presentation there are some boxes where you can choose
which sources to use in the particle tracer (in object inspector ->
properties -> source). I dont have that option in my program. Does someone
know why (using v3.4.0 on a Mac)?
About v3.4.0, isnt it the lastest version? Cant fint anything newer on
paraview.org.
Cheers,
Martin Uppman

<pre wrap="">Input 0 should be a time dependent dataset. It is best to use a
TemporalCache before the particle tracer to stop multiple updates for
the same time step. Input 1 should be some seed points.
Ensight -> TemporalCache ->
ParticleTracer
Some Other data eg.line/plane ->
the ignore pipeline time option is provided to get around some animation
issues that used to plague paraview. You should not need it, but the
correct way to use it, is set IgnorePipelineTime to true, then set an
animation keyframe to animate TimeStep from 0->N - the particle tracer
will then use the timestep to generate update times for the Ensight
input, instead of usigin the GUI generated time.
If you are using the particle tracer from prior to 3.4 then you should
switch to a newer one as it is contiunually being improved. I will soon
(months, not days) be checking in a lot of changes which enable it to
handle dynamic meshes better.

<pre wrap="">I've been looking for information on this and a found a thread which I
think concerns the same problem. In that thread Berk made a patch to fix
this problem.
I also tried to ignore pipeline time, but this doent work. I'm working
with .case files and I want to animate the blood flow in a human heart
using particle tracers. I'm using a Mac with ParaView version 3.4.0.
Thanks for looking into this.
Cheers,
