Thanks for your answer. But I am not so sure about what I am doing here, could you please check here. The main idea is to extract ROI average time series from different layer surface.
what I have done 1 using mris_expand to get intermediate layer, such as lh. white_outer0.16GM. 2 using bbregister to register functional volume to anatomical volume. 3 using mri_vol2surf to sample the functional data to the intermediate layer. mri_vol2surf --mov filtered_func_data.nii.gz --out $SUBJECTS_DIR/lh_0.16.w --out_type paint --srcreg register.dat --hemi lh --projfrac 0 --surf white_outer0.16GM after get lh_0.16.w, how should I use this file in mri_segstats function! This is a overlay file, not a volume or surface. Thanks! > On Oct 5, 2015, at 18:38, Douglas Greve <gr...@nmr.mgh.harvard.edu> wrote: > > mri_segstats with the label option.
