I found the problem, and it seems so simple now. In addition to the
server .xml file, I needed to create a .bqrc file for the client side.
I figured this out by reading both the "Animating Legacy VTK File
Series" and the "Plugin How-to" wiki pages and putting the knowledge
together. Would anyone object to me laying this out a little more
explicitly in the "Animating Legacy..." page (only the one on
paraview.org, not the one on vtk.org)? I could append a section called
"File Series Plugins for Existing Readers" or something like that.

I haven't tried adding it to readers.xml. I want to distribute this to
other users, and it would be best if they didn't have to recompile -
just use the plugin.
The good news is that the reader isn't mine; it already exists. It is
the UNC Meta Image reader (vtkMetaImageReader). It reads .mha & .mhd
files. I'm simply trying to extend it to read time series. I've
attached the .xml file that I've written.
It appears to select the original reader rather than the file series
reader for these files. I _think_ I've set all of the properties
correctly. I wonder if I need to tell it to override the file
extensions somehow?
Thanks,

Quoting Berk Geveci <[email protected]>:
Hmmm. It should work. Are you saying that it works if you add it to
readers.xml but not as a plugin? Can you share your xml and maybe the
reader code with the guts taken out?

I'd like my new FileSeriesReaderProxy to be a run-time loaded plugin.
I've created the necessary XML tags as per the discussion below, and put
it in a .xml file. It loads fine with the Plugin Manager, but the files
still aren't recognized as a series.
Is this because run-time loading of a FileSeriesReaderProxy isn't
supported? Has anyone else tried it this way (as opposed to adding it
to the readers.xml file and recompiling)?

Ken,
Yes, that's correct. The "Meta" (.mha, .mhd) reader exists in ParaView
(actually in VTK) and I want to load in a file series. And that
answers my
question, i.e., ParaView will load files of the same extension using
the new
plugin reader instead of the original one.
The reason I asked was that I seem to recall earlier versions of
ParaView
always using the _first_ reader for a given file extension if the
extension
conflicted with another reader. I assume that has been changed
recently.
Anyway, thanks for the answer. I didn't want to spend time on this if
there was no hope of it working.

Sean,
I am a little confused. Are you saying that there exists a reader in
ParaView that you want to use to load in a file series? And the
issue is
that because the reader already exists in ParaView in the "sources"
group
and you cannot move it to "internal_sources" or some other naming
conflict?
If this is the case, I don't think there is anything special you
have to
do. Just make a new <FileSeriesReaderProxy> tag in the "sources"
group.
The Reader subproxy can be in any group; it does not mater if it
also came
from "sources". The FileSeriesReaderProxy can also co-exist with
the single
file reader so long as they have unique names. You can also make your
reader read files with the same file extension; ParaView will use
the plugin
reader instead of the one defined in ParaView.

I'd like to write a plugin that makes the Meta format time-aware.
I've
looked at:
http://www.vtk.org/Wiki/Animating_legacy_VTK_file_series .
From that, I see that I can modify
VTK/Servers/ServerManager/Resources/reader.xml, but I'd prefer
it to
be
plugin that I can send to someone else with requiring a complete
rebuild
of Paraview/VTK. It should be possible to write a .xml file
that gets
loaded as a plugin and that wraps the Meta reader in a
vtkFileSeriesReader.
However, if I do it without modifying readers.xml, the original
Meta
reader does not get moved to a different ProxyGroup. Does that
mean
my
new Meta Series reader won't ever be used? Is there some other
way to
do it that doesn't require a rebuild of Paraview?
Thanks,
Sean
