Re: [Freesurfer] lh.ROI45.label and lh.ROI44.label overlapping

Hi Gari

sorry, I'm a bit confused. Are you using the individual subject estimates of 44 and 45 generated by FreeSurfer, or mapping them from MNI space? In either case you can get overlap unless you pick the most probably label at each point.

cheers Bruce

Hi freesurfers experts, this is (please check attached image) the best I got when trying to map a volume ROI (BA45 in MarsBar = MNI_Frontal_Inf_Tri_L_roi) to freesurfer using mri_vol2surf. I used /freesurfer/average/mni152.register.dat instead of spmregister since the ROI was already in mni152 2mm, the registration was perfect -checked with tkregister2.

• I obtained the red area of the image, which is outside of the ROI45.label. Considering that the source was not exactly the same, could I consider it acceptable for cortical thickness analysis?
• Why are the 44 and 45 overlapping?

Thank you very much and sorry for the multiple questions, Gari
