Hello SPM-listserv,
I am a graduate student trying to determine the activation in and around
the motor cortices for an event-related study. I have already performed
a total brain analysis with SPM2. I have also created a ROI mask around
the motor cortices in MRIcro based on anatomical markers. How do I
multiply this mask with my functional images in order to run SPM only on
the motor cortices? The process should be similar to removing a lesioned
area prior to estimating activations. I would prefer to do this without
normalizing the data to stereotaxic space. Is there existing software
that allows me to do this with SPM?
Thanks,
Dan Krainak
