I'm trying to perform normalization of my fMRI data sets as a prelude to
inter-subject averaging. I've been asking SPM to 'determine parameters
only', and I've been using one of my subjects as the template and the others
as the sources. However, for some reason, this causes Matlab to crash, and
I'm uncertain whether the problem lies with: 1) Matlab, 2) a bug in SPM, or
3) my improper implementation of the Normalization procedure. Matlab does
give me the following error message:
Error in ==> C:\matlabR12\spm2\spm_slice_vol.dll
Error in ==> C:\matlabR12\spm2\spm_smoothto8bit.m (smoothto8bit)
On line 51 ==> img = spm_slice_vol(V,spm_matrix([0 0 i]),V.
dim(1:2),0);
Error in ==> C:\matlabR12\spm2\spm_smoothto8bit.m
On line 14 ==> VO = smoothto8bit(V,fwhm);

??? Error while evaluating uicontrol Callback.
I'd greatly appreciate any help anyone can give me with this.
Thanks,
RGL
