It was indeed a bug. Thanks for reporting it Bill. A fix is in the<br>
pipeline. It will probably take until next week for it to make into<br>
ParaView master.<br>

Sounds good, thanks Berk.<br>
<br>
And if, while that's in the pipeline, can I also request an agumentation<br>
to the documentation -- what is the "TrailId" data that is added to<br>
the pathlines output? And also, I noticed that the particles output<br>
also has an added data value ("GlyphVector") -- what does that do?<br>
<br>
(And there's a typo in the beginning of the documentation -- "much"<br>
should be "must". Trivial, I know.)<br>

A followup to my question.<br>
<br>
Presuming this is a bug, which means it might require some time to<br>
fix, I went ahead and figured out a work-around.<br>
<br>
I just bring up a "Calculator" filter and duplicate the problematic<br>
field ("mass") as "massdup", and then put that through the<br>
TemporalParticlesToPathlines filter. And now I have access to<br>
the data of interest.<br>
<br>
Curiously, it's the "massdup" field that is now replaced by "TrailId".<br>
<br>

Sounds like a bug. Do you have data/pipeline to reproduce it?<br>
<br>
<br>
Sure. I put a tar file at:<br></div>

I included the first 9 steps of the data.<br>

Hello,<br>
<br>
I am confused by something that the TemporalParticlesToPathlines<br>
filter seems to be doing. It seems to be deleting or replacing<br>
one of the scalar fields in the "Pathlines" output.<br>
<br>
I have a rather simple pipeline:<br>
<br>
Data<br>
TemporalInterpolator<br>
TemporalParticlesToPathlines<br>
Pathlines<br>
Tube<br>
Particles<br>
Glyph<br>
<br>
So the data has a handful of scalar values:<br>
* density<br>
* id<br>
* mass<br>
* type<br>
* velocity (okay, not a scalar)<br>
* vphi<br>
<br>
And all the filters offer these as available to color the data<br>
by -- except! Except under the Pathlines (and Tube), the "mass"<br>
data is replaced by "TrailId".<br>
<br>
Of course, I'm trying to color the pathlines by the value of the<br>
particle "mass", so this is a problem for me.<br>
<br>
And I'm using the "id" field to make sure the particles are<br>
properly<br>
associated with their past selves in the<br>
"TemporalParticlesToPathlines"<br>
filter.<br>
<br>
Any thoughts? Didn't find anything via Google (though I<br>
limited the<br>
search to the past year).<br>
<br>
Oh, and I tried this both with ParaView versions 4.0.1 and<br>
4.1.0.<br>
<br>
Thank you,<br>
Bill<br>
