Is it possible to have more than 32767 columns/rows in an image? I have observed that a package that is using ITK [ref] has this limitation and I was curious if this was indeed the case.
That might be a limitation of the Nifti file format. Try other file formats (MetaIO, NRRD). Image sizes should be 64-bit long now, and might have been 32-bit long more than a decade ago.
Got it, thank you.
