Hi Jimmy,

I got some problems using the headers with your nice tool.

When I load a 4-D nifti file header with load_nii_hdr and compare it with the header from the .hdr field using load_nii, I get different pixdim values:
load_nii_hdr:

nifti_hdr = load_nii_hdr('nifti_file');
nifti_image = load_nii('nifti_file');

nifti_hdr.dime.pixdim is [1 4.5313 4.5313 4.5000 200 1 1 1]
nifti_image.hdr.dime.pixdim is [1 4.5212 4.5312 4.4900 200 1 1 1]

The difference of the pixdim arrays is [0 0.01 0 0.01 0 0 0 0]

Did I found a bug or is there a bug in my head?

Pieter
