vtkImageReader.cxx not available for modelling with raw file

ParaView Support
1

Hi there,

I’m new to ParaView (5.7.0) and have hit an unexpected roadblock. Following instruction given here (see below) I am trying to build a 3D model from slices, prepared using ImageJ and MuhRec (collected via neutron tomography, so greyscale). As recommended I created raw file and applied the relevant scalar type and data extent. However, when the process always fails. I get the generic warning: In C:\bbd\ecd3383f\build\superbuild\paraview\src\VTK\IO\Image\vtkImageReader.cxx, line 307
File operation failed. row = 0, Tried to Read = 3086, Read = 0, Skip0 = 0, Skip1 = 0, FilePos = -1
ParaView is not installed in hardrive C and I’ve not been able to trace it.

Any advice would be great! Thank you.

Welcome to ParaView, Chloe!

Did you make sure to set the Data Extent upper bounds to the image dimensions - 1? That is often a source of difficulty.

Hello Cory!

I’ve run through your suggestion with a couple of times on a large (1930 slices) and small (32 slices) set but still no luck. Instead I get this error message:

ERROR: In C:\bbd\ecd3383f\build\superbuild\paraview\src\VTK\IO\Image\vtkImageReader.cxx, line 190
vtkImageReader (000002272AC90CE0): Header size: 4294769728, file ext: -1, 1542, -1, 1542, -1, 31

Do let me know if there is any additional information I can provide, and thank you for your help!

Best wishes,
Chloe

Don’t set the values in the left column of the Data Extent property to -1, set them to 0 and try again.

When set to 0 I get the outline of a block, but then the program tends to crash.

Can you share a dataset so we can try to reproduce the crash?

Chloe and Cory,

I am facing the exact same problem. Wondering if you have figured out the solution yet. I am trying to use paraview to read in some tomography data in .raw format exported from Avizo.
