Thank you for making this clear. You are absolutely right - we have changed the threshold specification for uncorrected thresholds with conjunctions to make it the same at the corrected specification. The specified p value now pertains to the conjunction SPM not the component SPMs Again thank you - Karl %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
