I've hit that before. the RAW reader uses MPI-I/O, and MPI uses signed
int everywhere in its API, so there are limits that you end up hitting.
For instance to partition the data among processors one must give
MPI-I/O the starting offset of the data in the file as a signed int, and
that is limited to 2^31.

Hmmm that happens to be around 4 GB which makes me wonder if there is
a limit somewhere in that reader... Any chance you can try this on a
Linux machine?

Dear all,
I am encountering issues when trying to import large 8 bit RAW
volumes to Paraview 5.1.2 (64 bit).
The file I wish to import has xyz dimensions of 2000x2000x1920
voxels (Unsigned char), 7.5GB. I am running a machine with 192 GB
RAM and 12 CPU cores.
I can import up to a 2000x2000x1000 crop of this file, but I
encounter the following message when I attempt larger z dimensions:
ERROR: In
C:\bbd\df0abce0\source-paraview\VTK\IO\Image\vtkImageReader2.cxx,
line 592
vtkPVImageReader (0000000007767F90): Initialize: Could not open
file
\\cseg_2\ERC\SLS_201606\Myco_2\CT2PpR3h1_\Hyphalseg_Raw_2000_2000_1920_8bit_SKELETON_FILT_PARAVIEW_TEST.raw
I cannot find an obvious memory ceiling within the paraview
settings - any ideas as to whether there is some effective upper
limit to import file size?
