Hello, AFNI experts,


May I ask for advice on normalizing the result of 3dDeconvolve?

I am trying to normalize GLM results spatially on the MNI template. However, it seems that the results are not on the MNI template correctly.


I utilized this codes.


3dwarp \
-deoblique \
-prefix $rootDir/$SBJ/glm_normalized/$SBJ'_func_dstscvr_normsm4_PPI_Trials_bucket_fef_'$HEMI'_deobl+orig' $rootDir/$SBJ/$SBJ'_func_dstscvr_normsm4_PPI_Trials_bucket_fef_'$HEMI'+orig'

adwarp \
-apar $rootDir/$SBJ/glm_normalized/MNI152_T1_2009c+tlrc\
-dpar $rootDir/$SBJ/glm_normalized/$SBJ'_func_dstscvr_normsm4_PPI_Trials_bucket_fef_'$HEMI'+orig' \
-dxyz 1 \
-prefix $rootDir/$SBJ/glm_normalized/$SBJ'_warped_ppi_fef_'$HEMI



Because the AFNI suggested to deoblique the dataset, it was performed before conducting the normalization. All the options of resampling methods (NN, Li, Cu, Bk). Unfortunately, all the resampling methods were not helpful. Furthermore, -dxyz value was also changed to 2 or 3. It was not helpful also. In this situation, what can I do to resolve the issue?
