Dear list,
I am currently setting up spm5 based fMRI postprocessing on our system,
and was wondering whether it would be easy to make spm5 read nii.gz
files instead of nii files. gzipping images would save us ~60% of space,
and on linux it should in theory be possible to pipe the images through
gzip before they enter preprocessing/model estimation (I don't care
about Windows). Slowing would not be a big issue, space is more of a
limitation.
Is there anyone that already has some experience with doing this? I
guess it would be easiest in the spm5 code on a central location (e.g.,
function) where images are always passed through when they are read, no
matter whether for preprocessing, stats or display purposes. For writing
nii I'd have the same question.
I already read the post below on spm5b that no .gz can be read/created
using spm5(b), but some time has passed since. And there is mention that
it should be possible from within spm5's @nifti toolbox (which I am not
very familiar with)...

Thanks for any pointers!
Cheers,
Bas
