Hello SPMers,
I am using SPM5 update 1782, MatLab 7.0 and Windows XP 2002 Professional with service pack 3.
After realigning my functional images, coregistering the T1 image to the mean of the realigned functionals, segmenting the T1, estimating the parameters to normalise using the biased T1 image and T1 template (see attachment), write normalising the realigned functionals using the resultant parameters, smoothing the normalised functionals and generating a first-level analysis for one subject, the activation appears displaced posteriorly on the glass brain (see attachment).
I then attempted to estimate the parameters to normalise using the mean functional realigned image and the EPI template (see attachment). After write normalising the realigned functionals using the resultant parameters, smoothing the normalised functionals and generating a first-level analysis for the same subject, the activation appears displaced posteriorly and ventrally on the glass brain (see attachment).
Any ideas?
Thank-you,
Julie
