I am trying to correlate my behavioral data with whole brain cortical measures using cortical measures as IVs and behavioral data DV.

Somehow the significant clusters I get from cortical thickness, area and volume are in MNI co-ordinates but significant clusters from local gyrification-behavioral data are in Talairach co-ordinates.

I used identical procedures to preprocess my data but still I am getting my results in different co-ordinate systems (thickness, volume, area in MNI and gyrification in Tal).

I would really appreciate any help.
