Hi all!
I am stuck at this point with SPM5 (fmri):
In Factorial design specification, I specify a file as an explicit mask.
This creates my SPM.mat as it should do. In the next step I select this
SPM.mat for the fMRI model estimation. When I run this job, SPM breaks
with an error at spm_spm.m line 637. Here a "xM.VM(i).mat" is called, but
xM.VM(i) contains not a structure, but simply the filename of the mask.
What might be the problem here?
The reason for wanting to use an explicit mask is that after smoothing the
con-images, the implicit mask for the scon-images is much too large,
resulting in activity located outside the brain. Am I doing something
wrong here?
I would be very glad if anyone could help me here. Thanks!
Steffen
