Hi Dorian if you want to avoid overlap you might need to cobble together a procedure yourself - probably converting the annots to labels then removing the overlap and recombining into an annot. It wouldn't be that hard to do in matlab. For you second question you are probably best off drawin

Thank you Bruce and Douglas, I meant to combine them because I did not want overlaps. Can I advance one more question as we are here. How can I get an average thickness of the entire lateral temporal lobe (inferior, medial, temporal gyri)? The average of the three gyri may not be useful as one gy

>>For Destrieux there is only the aparc.a2009s+aseg.mgz. Does this file have also the WM parcellation? Not by default, bu you can create one easily enough with cd $SUBJECTS_DIR/subject mri_aparc2aseg --s subject --labelwm --hypo-as-wm --rip-unknown --volmask --o mri/wmparc.a2009s.mgz --a2009

Hi Dorian you don't need to combine them in any specific way if all you want is to look at ROI-based stats. Just take the ones from each atlas that you like. cheers Bruce On Mon, 23 Jun 2014, Dorian P. wrote: Dear Freesurfer followers/developers, I am doing a study involving temporal lobes

Dear Freesurfer followers/developers, I am doing a study involving temporal lobes and the parcellations from Desikan and Destrieux atlases have very different results. I like the full gyrus parcellation of Desikan but the temporal pole is very small and limited, while in Destriux the temporal pole
