<div dir="ltr">Sergi,<div><br></div><div>Your VTI file extents should only describe the region of the whole image they occupy, so you are on the right track. In situations like these where it isn't obvious what is wrong, I tend to start from the beginning with a very small example and build up from there. For example, you could start with a small image - say 2 x 4 pixels (2D) split into two pieces. Start with one data array for this example and make sure it works - use ASCII encoding so that you know for sure what is in the XML file and then switch to raw binary, then zipped binary. Then add a second data array. When you are confident that works, change the example to four pieces, then make the image 3D and so on.</div><div><br></div><div>It can take a while to do this, but you'll come out really understanding the file format and will probably figure out what you had wrong in the first place.</div><div><br></div><div>Thanks,</div><div>Cory</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Sat, Jul 11, 2015 at 5:32 AM, Sergi Mateo Bellido <span dir="ltr"><<a href="mailto:sergi.mateo.bellido@gmail.com" target="_blank">sergi.mateo.bellido@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<div>Hi Cory,<br>
<br>
Thanks for your time. I have been playing a bit with the files too
and I realized that replacing the whole_extent of each *.vti by
the whole dataset everything works.<br>
<br>
I would like to generate something like this:
<a href="http://vtk.1045678.n5.nabble.com/Example-vti-file-td3381382.html" target="_blank">http://vtk.1045678.n5.nabble.com/Example-vti-file-td3381382.html</a> .
In this example, each imagedata has whole_extent=whole size but
its pieces only contain a portion of the whole dataset. Does this
configuration make sense?<br>
<br>
I have been trying to generate something like that but I failed.
My code looks like this one:
<a href="http://www.vtk.org/Wiki/VTK/Examples/Cxx/IO/WriteVTI" target="_blank">http://www.vtk.org/Wiki/VTK/Examples/Cxx/IO/WriteVTI</a> but using
VtkFloatArray as buffers and attaching them to the VtkImageData. I
tried defining the set of the VtkImageData as the whole dataset
and defining the VtkFloatArrays of the size of each portion but it
didn't work :(<br>
<br>
Any clue?<br>
<br>
Thanks!<span class="HOEnZb"><font color="#888888"><br>

<div>I played with your data set a little but haven't found what
is wrong. I am suspicious of two things in the data file, the
extent and the offset in the second data array (it looks too
small).</div>
<div><br>
</div>
<div>What are the dimensions of your grid? Note that the whole
extent upper values need to be the dimension - 1, e.g., for a
300x300x300 grid, the whole extent should be 0 299 0 299 0
299.</div>

<div>Hi Cory,<br>
<br>
Thanks for your answer. I reproduced
the segfault in two different ways,
but it's always after loading a data
set:<br>
- After loading a data set, I tried to
play the simulation ->segfault<br>
- After loading a data set, I tried to
filter some fields from the model
(Pointer array status). As soon as I
clicked the 'apply' button, paraview
crashed with a segfault.<br>
<br>
Thanks,<br>
Sergi
