Dear Nahla, In WFU Pickatlas you can combine the Uncus (TD LAbels), amygdala (aal) and parahippocampal (aal) region to obtain a mask that will be equivalent to the piriform. Or you can do a similar combination with the regions already available there. Hope this can help you, Best regards, David Vállez On Wed, Jul 9, 2014 at 3:15 PM, Ms Nahla Lutfi A Faizo < [log in to unmask]> wrote: > Dear SPM users > > Please please I need your help. > I want to create a piriform mask to use it as a seed for functional > connectivity analysis.
