Dear AFNI experts,
I would like to register some ROIs in the MNI space to the T1-space of one participant.
I used auto_warp.py to to extract the transformation T1-2-MNI space and then use 3dNwarpApply to apply the inverse transformation to my ROIs. While the direct transformation looks fine (t1 to MNI), when I apply the inverse transformation my ROIs are not correctly registered. Could you please give me some advice on that?
these are the commands:
auto_warp.py -base MNI152_T1_2mm_brain.nii.gz -input PT4_T1_3D_AX_brain.nii -qblur 1 3 -unifize_input yes -save_script script -skull_strip_base no -skull_strip_input no
3dNwarpApply -master anat.nii -source LEFT_IFG44.nii -iwarp -nwarp 'anat.un.aff.qw_WARP.nii anat.un.aff.Xat.1D' -interp NN -prefix test_roi_left_IFG.nii
thanks
giovanni
