Is there a reader for Analyze 7.5 hdr/img 3D image format?

I can read the img file with the “raw” reader. It is a bit fiddly because I have to first poke around the header to find out the dimensions and the data type. So I’m wondering if anyone has a plug-in or something to read this format?

ParaView 5.9.0 has a .hdr file reader.

Thank you. Is it perhaps called something else? I don’t see it on the list:

It should be automatically picked. Please share your file.

Your hdr file is not compatible with our reader.

I see. As stated above, the format is “Analyze 7.5”. Apparently readers for NIfTI images might be able to handle it…

Indeed, I should have read more carefully.

Is it possible to write a Paraview reader in Python?

There is a bit about reading raw data from xdmf files. I hve to admit I don’t understand the example Reading a time varying Raw file into Paraview. What is supposed to happen? The xml file is read, no error. But when is the raw file read?

Splendid! Thank you very much for the link.

BTW: the section heading is wrong: it is a 3d image, not 2d.
