Katja:
It might be because the con-images are not thresholded, so they do not match
with the 'glass brain' results which show only voxels surviving the
threshold.
I suggest that you write thresholded images using the SAVE button after
calculating your results, and then visualize them.
Hope this helps & makes sense

Subject: [SPM] con*-files
Hello everyone,
I'm trying to visualize some fMRI data at the moment. With two
programs (Caret and MRIcro), I'm facing the same difficulties which
might be due to my con*.img/.hdr files (generated with SPM99,
one-sample t-test, uncorrected, p < .001)? The brain activations as
displayed in the .img files seem to cover (too) large areas of the
brain. Glass brains and tables produced by SPM, however, involve only
few clusters. If you have any idea what could be gone wrong, please
let me know.
Thank you in advance
Katja
