Hey Utkarsh,
No, I've never seen the clip lose data on one dataset by itself.
The other interesting thing is that I can't always get this data loss
to happen if the data was generated as part of a source from the
Sources menu. It's much more likely to disappear when the data was
generated by a filter or brought in by a reader.
For example, if you generate a Box and a Wavelet source, grouping and
clipping them won't lose any data, but if you run Generate IDs on one
of them, then select GenerateIds1 second before grouping, then clip,
the "Ids" point data disappears...
Thanks,
-Eric

Eric,
Does the loss of arrays happen even if you clip the orginal dataset by
itself (without grouping it using the group filter)?

Hello,
I'm creating a multi-block data set using the group filter and then
clipping
it. The results of the clip are always missing one of the scalars
associated
with the second data set that I highlighted before applying the group
filter. This only seems to happen if one of the data sets has
multiple
scalars or vectors associated with it -- if they each only have
one, nothing
is lost in the clip. (ParaView 3.4 and CVS, OS X 10.5.6 and Windows
XP
32-bit, no MPI)
I originally saw this with my own data, but I am able to easily
replicate
this by creating two point sources. I apply the Elevation filter to
the
first. Then, to the second I apply Brownian Vectors, plus a
Calculator that
computes the magnitude of those vectors. If I highlight Elevation
and then
Calculator, then Group and Clip, I lose the vector magnitude scalar
at the
Clip stage. If I highlight the Calculator and then the Elevation,
then Group
and Clip, I lose the elevation scalar.
Please let me know if anyone has any ideas about where this could
be coming
from.
Thanks a lot,
-Eric
