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
