Hi Linling
It might be that MRicro is showing you the coordinates in Talairach space
and SPM in MNI space. I noticed in your attached MRIcro jpg image that there
is a little checkbox to the left of the coordinates which says “tal2mni”.
Try checking this and see if they correspond better.
Cheers

Subject: [SPM] Problem with MRIcro
Dear all,
When I was using MRIcro to show the activation of a T-contrast image, I
found the activation pattern was slightly different from the activation
showed by SPM. I would explain this through two pictures I attached with
this email.
As we could see from the whole brain statistics picture, voxel which
coordinate was (9, -34, -20) (red one) had a T value of 2.16. However, when
I select this voxel via MNI coordinate in MRIcro, it showed there was no
activation (the T value was below the threshold, there was no T value showed
following its coordinate in the lower left quarter). Had MRIcro done
someting to the T-contrast functional image?
Hope someone could help me with this.
Thank you all in advance!
Best wishes!
