If the purpose is to register EPI data for group-level analysis then 2mm is enough.

Is there a configuration file about registeration to MNI152_T1_1mm? >>> >>> I mostly recommend registering to the 2mm template (using the usual configuration file) and then resampling to the 1mm template with applywarp. >>> >>> Good luck Jesper >>
