<div dir="ltr">Dear David,<div><br></div><div>I tried to use XMLImageDataWriter and it seems to be working. However, the original VTK file that has 2Gb is then saved as a vti file that has only 10Mb. I think this is fine because my data is very sparse with a lot of zeros. I can make sure that it is working well because Paraview crashes when I tried to load the file. I'll check it again later on. Anyway, do you think the bug is in the StructuredPointsWriter?</div>
<div><br></div><div>Bill, I tried to not specify the data extent, but in this case the reader reads only the first image of the sequence. Is there anything else I have to set up?</div></div><div class="gmail_extra"><br clear="all">

The data extents you specified will produce a zero length structured points.<br>
<br>
For the tiff reader, you need not specify the extents if you want all<br>
of the data. And I'm not sure what the other methods will do in the<br>
tiff reader.<br>
