Q: Howdy all,

if I try to use nii2mnc I get this interesting error message:

nii2mnc test_image_00001.hdr

• ERROR: nifti_convert_nhdr2nim: bad dim[0]
• ERROR (nifti_image_read): cannot create nifti image from header ‘test_image_00001.hdr’

My current version: nii2mnc -v
program: 2.0.15
libminc: 2.0.15
netcdf : “3.6.2” of May 10 2008 09:14:53 $
HDF5 : 1.6.6
(installed using mincbundle on a recent Ubuntu Intrepid install with all the recommended upgrades). (I also have an unusual situation, as it turns out that most of the binaries are located in /bin and the libraries in /usr/lib by default - no idea why!)

Hope somebody can point to a solution… Thanks!

A: HI, Maybe have a look at the value of dim[0]. I’ve seen images where dim[0] is incorrectly set to 0 instead of 3 or 4.
