Dear SPMers,
I?m a new SPM5 user.
My goal is to register with affine transformation a group of
hemispheric SURFACES extracted from MRIs.
I did the following:
(1) I used SPM5 ("Normalise :Estimate& Write"from the GUI)to register each MRI
volumes to the T1 template;
(2) I have extracted hemispheric surfaces from each non registered MRI in (1);
(3) I have applied to each surface extracted in (2) the correspondent
transformation parameters obtained in (1).
My doubts are the following:
a) I noticed that the transformation parameters in the *sn files are slightly
different from what I can read from the GUI and I do not know which are the
right ones;
b) I realized that the so transformed surfaces (with both the transformation
parameters)are spatially spread all around and so something went wrong
but I do not know where.
Any comment/hint/idea would be highly appreciate.
Best Regards,
Antonietta Pepe
