<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>VTK has a data type called structured grid that is different than image data (and also different than unstructured grid). If ParaView is not telling you that your data is image data or a uniform grid, then the data you write out will be necessarily incompatible with reading it as an image file.<BR>

<BR>
I'm new to Paraview and am trying to use it to edit a VTK image. My <BR>
original image is in the structured points format. I'm using the <BR>
ExtractCellsByRegion filter to select a subset, which I save using <BR>
Save Data with a VTK extension like the original. However, I could <BR>
not open this file using the ITK ImageFileReader. I believe this is <BR>
because the VTK file was saved as an unstructured grid instead of <BR>
structured points.<BR>
<BR>
Does anyone know why this is happening and how to change it? I can <BR>
look at converting it using ITK, but I'd like to know if there's a <BR>
better solution.<BR>
<BR>
Thanks,<BR>
Sara<BR>
