Dear SPMers,
I have a slight problem with a random-effects group analysis and wonder
if you might be able to help.
Essentially my concern is that the group activations (as shown by an SPMT
image for one particular contrast) do not line up with the outer edge of
cortex in my averaged wmT1 or the SPM single-subject canonical template.
This is the case for all group T images.
Individual subject normalisation was accurate as verified visually using
check reg - both individual structural and mean functional images match
the T1 template and wmT1 accurately. The problem seems to arise when I do
a group analysis.
Is there a stage of processing I have done erroneously?
Thank you in advance,
Rachel
