Hi Joseph,
 
Have tried the 'example of creating a simulated .NII file'
by Tom Nichols and John Ashburner at
http://www.sph.umich.edu/~nichols/JohnsGems5.html 

Maybe you can try duplicating the slices in case SPM
do not like only one image slice...

Hi

Does anyone know how to convert matlab files into .nii files
that can be read by SPM. I am trying to use SPM to analyse
some optical imaging data.

I have arranged my data into a 4D struct [x y z t] although 
it is not fMRI data there are only 2 spatial dimensions so
I have 60 frames of 512x512 14 bit images arranged in a
matlab file as (512,512,1,60).

I used the make_nii function that is available in the MatLab
NIFTI and ANALZYE toolbox, and although it seems to work
and it creats an image file with a header etc, when I save
it as a .nii file I am still unable to open it with SPM.

Maybe I'm barking up the wrong tree in thinking I can treat
my optical imaging data like fMRI data, but my supervisor is
convinced I can use SPM with optical imaging data.

Any advice ot information would be much appreciated

Thanks

Joe
