I am using the latest version of the nifti library in my program and when I save images to (nifti-2) files, neither fsl nor mricron (on a Ubuntu Focal system) accept them. The program can read nifti-2 images that it has just saved (putting the bar low), but it would be nice to have an external reference!

Are there any open-source image viewers that already support nifti-2? Or, failing that, is it possible to create nifti-1 images with the nifti-2 library? The only routine that seems available for creating a new nifti image seems to be nifti_simple_init_nim(), which only makes nifti-2.

Many thanks!
