that looks right except "--surfreg sphere" should be "--surfreg fsaverage_sym.sphere.reg" Where did you get those instructions? Did I send them out before? doug

Dear Doug,

thanks for your answer. I guess I got confused by the output of the interhemispheric registration.

So, to be sure I understood correctly: are you suggesting that I should

1. run

mri_label2label --srcsubject suj1 --trgsubject suj1/xhemi --srclabel $SUBJECT_DIR/suj1/label/lh.mylabel.label --trglabel $SUBJECT_DIR/suj1/xhemi/label/lh.mylabel.label --regmethod surface --surfreg sphere --hemi lh

2. copy the newly created label /suj1/xhemi/label/lh.mylabel.label to

suj1/label/rh.mylabel.label and calculate stats from that one?

Thanks again! Have a nice day, Irene

Hi Irene, what are the instructions you are following? If you have mapped the lh.roi to the LH of the xhemi subject (making it the RH), then you can copy it to subject/label/rh.roi and run the normal stats. doug

Dear all,

I have a ROI on the left hemisphere and I'd like to extract cortical thickness values from the homologous region in the right hemisphere. For this I applied the interhemispheric registration process and got my ROI mapped into the right hemisphere in /subject/xhemi/label. However when I tried to run mris_anatomical_stats on /subject/xhemi it failed, as there is no wm.mgz file in /subject/xhemi/mri.

Any suggestion would be greatly appreciated.

Thank you, Irene
