you will need to run mri_annotation2label and specify the output to be an annotation file instead of a segmentation. Then you will have to run mri_aparc2aseg, specifying your lobes annotation as well as --labelwm (look in the recon-all.log file for an example of how wmparc.mgz is created). Then run mri_segstats (you can also get an example from the recon-all.log file). doug

Hi:

I used the following commands to get the cortical volume per each lobe:

mri_annotation2label --subject OAS1_0001_MR1 --hemi rh --lobesStrict lobulos --seg lobulos --stat lobulos mri_annotation2label --subject OAS1_0001_MR1 --hemi lh --lobesStrict lobulos --seg lobulos --stat lobulos mris_anatomical_stats -a lobulos -f OAS1_0001_MR1_lobulos_rh -b OAS1_0001_MR1 rh mris_anatomical_stats -a lobulos -f OAS1_0001_MR1_lobulos_lh -b OAS1_0001_MR1 lh

Which commands (sintaxis) must I use to compute the white matter volume per each lobe ?... I tested the mri_aparc2aseg and mri_segstats commans with different options, but I couldn't get the volume that I need...
