[Paraview] I can't read a binary 'raw' data image file

[Robert.Atwood at diamond.ac.uk]

Dear List

I hope it's some silly 'newbie' issue, but I find myself completely unable to read a raw binary data file using the raw binary data file reader. I have saved a data file as 'raw data' from ImageJ to try, and loaded that same file in ImageJ to verify that data is present. I have saved two versions: 8 bit [0-255] binary data and floating point 32-bit data in little-endian format.




Then in Paraview I try to open the file, then select
File prefix : this contains the correct file name it appears to me
C:\Documents and Settings\kny48981\My Documents\Experiments\snail\snail_partial_348x250x348_float32.raw
Data Scalar Type: Float (or Unsigned char for the other version)
Data Byte Order: LittleEndian 
File Dimensionality: 3 
Data Origin 0 0 0 
Data Spacing 1 1 1
Data Extent 0 348
            0 250 
            0 348 
Number of Scalar Components: 1
Scalar Array Name: ImageFile
File Lower Left (ticked) 

Then I select APPLY

I observe an Output Messages dialog box with the following messages in it. I do not understand these messages. I have not, so far as I know, specified any header 


ERROR: In ..\..\..\..\src\VTK\IO\vtkImageReader.cxx, line 184
vtkMPIImageReader (0959F008): File operation failed: 4293783092, ext: 0, 348, 0, 250, 0, 348


ERROR: In ..\..\..\..\src\VTK\IO\vtkImageReader.cxx, line 188
vtkMPIImageReader (0959F008): Header size: 4293783092, file ext: 0, 348, 0, 250, 0, 348


Then, I have apparently a dataset of the specified size, the bounding box displayed, but under 'information' 
Data Arrays
ImageFile float [0,0] 

Which  I understand as having no values other than zero???
What did I do wrong??

Thanks
Robert
