WebNow that we have estimated the transformation from the T1 image, we can take that deformation and apply it to the fMRI data using spm12_normalize_write. Again, we are registering to the MNI template and will use a standard bounding box. We pass the anatomical, mean fMRI, and 4D fMRI data in to be transformed. WebThe reference 3D-T2WI was acquired using the method used for 3D-T1WIs. Then, six 3D-T1WIs were processed using intrasubject bias-correction processing with SPM12, resulting in six new 3D-T1WIs of nonuniform signal intensities. Thirteen volume data sets were segmented into native-space tissue probability data using SPM12.
