    <div>Hi,<br>
      <br>
      After a few hours debugging ParaView's code I think that I finally
      found the bug! :)<br>
      <br>
      The problem is that the meaning of the piece extent changes
      depending on if the piece has the whole dimensions or only a
      portion of them. For example, imagine that we have the following
      *.pvti file:<br>
      <br>
      <VTKFile type="PImageData"  ...
      compressor="vtkZLibDataCompressor"><br>
        <PImageData WholeExtent="0 200 0 200 0 200" ...><br>
          <PPointData><br>
            <PDataArray type="Float32" ..."/><br>
          </PPointData><br>
          <Piece Extent="0 200 0 200 0 101"
      Source="raw_binary_0_0.vti"/><br>
          <Piece Extent="0 200 0 200 101 200"
      Source="raw_binary_0_1.vti"/><br>
        </PImageData><br>
      </VTKFile><br>
      <br>
      In this case, the dimensions of the pieces are:<br>
        1st piece -> [0..200], [0..200], [0..101)<br>
        2nd piece -> [0..200], [0..200], [101..200]<br>
      <br>
      Note that the last dimension range of the 1st piece doesn't
      include the 101 value which is included in the 2nd piece.<br>
      <br>
      The issue here is that the code is not taking into account this
      when it's computing the dimensions of the current piece. In file
      VTK/IO/XML/vtkXMLPStructuredDataReader.cxx:155 we have the next
      call to 'ComputePointDimensions' function:<br>
      <br>
       this->ComputePointDimensions(this->SubExtent,
      this->SubPointDimensions);<br>
      <br>
      I printed the values of 'this->SubExtent' and they were the
      same values specified in the Piece Extent field:<br>
      <br>
      (gdb) p SubExtent<br>
      $1 = {0, 200, 0, 200, 0, 101}<br>
      <br>
      For these values, the 'ComputePointDimensions' function, which is
      defined in VTK/IO/XML/vtkXMLReader.cxx:916, computed the next
      dimensions:<br>
      <br>
      (gdb) p this->SubPointDimensions<br>
      $2 = {201, 201, 102}<br>
      <br>
      How these values are computed is very simple: upper_bound -
      lower_bound + 1. Note that the value of the third dimension is
      wrong: it should be 101 instead of 102.<br>
      <br>
      Finally, the segfault is produced in the 'CopySubExtent' function,
      which is defined in
      VTK/IO/XML/vtkXMLPStructuredDataReader.cxx:342, because
      SubPointDimensions information is used to copy the regions and we
      are doing an extra copy (loop defined in 371 line).<br>
      <br>
      Could you confirm me this bug?<br>
      <br>
      Best regards,<br>

      <div>Hi Cory,<br>
        <br>
        I have been doing some experiments with the encoding formats but
        I've not progressed much. <br>
        <br>
        The elements of my mesh are floats and the mesh dimensions are
        201x201x201 (X,Y,Z). I executed all the experiments with 2 MPI
        processes and the data domain was manually partionated by the Z
        axis, i.e. each process computes half of the cube.<br>
        <br>
        The program basically writes, at each position of the mesh, the
        identifier of the MPI process that computed that position (mpi
        rank). In our case, this means that half of the cube has a '0'
        whereas the other portion has a '1'.<br>
        <br>
        Attached to this email you will  a tarball with 3 outputs, one
        for each different encoding (ASCII, zipped binary, raw binary).
        The size of the mesh is 201x201x201 and the only difference
        among the executions is the encoding format.<br>
        <br>
        I hope you could give me some light.<br>
        <br>
        Thanks!<br>

            Your intuition was right: the problem is related in some way
            with the offset. I've changed the DataMote to ASCII and
            everything worked :)  Note that in this mode the offset

              <div>Your VTI file extents should only describe the region

                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>

                      Thanks for your time. I have been playing a bit

                      whole_extent=whole size but its pieces only
                      contain a portion of the whole dataset. Does this
