Good day to you all,
Would someone be able to help me through the steps of importing an ROI into SPM8. I have the add on MarsBar, although I am not sure if it will be of use.
I actually extracted an ROI of the right entorhinal cortex by doing the following steps (which are executed through FreeSurfer on a preprocessed subject):
mri_label2vol --seg aparc+aseg.mgz --regheader aparc+aseg.mgz --o gmroi_volume.nii.gz --temp orig/001.mgz
cp gmroi_volume.nii.gz SPM_analysis
cd SPM_analysis
3dcalc -a gmroi_volume.nii.gz -expr 'equals(a,"# from lookup table")' -prefix right_entorhinal_ctx.nii.gz
gunzip right_entorhinal_ctx.nii.gz
So, then I'm left with a .nii file (that I also converted into .hdr/.img). What steps should I take to import it into SPM8 and view it on my coregistered PET/vMRI?
Monica
