Hey Frank,
I was exploring the atlases shared with DSI Studio. I opened up the ICBM152_adult.fib.gz and visualized it's attached T1w (ICBM152_adult.T1W.nii.gz), then loaded up some ROI from FreeSurferDKT_Cortical.nii.gz and FreeSurferDKT_Subcortical.nii.gz. I've got the pre and postcentral gyri visualized, along with the thalamus left/right. You can see from the screenshots attached that the ROI are not quite in the correct location. Are these FreeSurfer ROI meant to be in ICBM152 space?

Thanks,
Nicole Seider
