Dear Matthew,


Please may I ask a follow-up to my original question?


Having done the analyses, inputting a binarised mask into the "Pre-threshold masking" option in the Post-stats tab, I now have my results. I'm a little confused because I get results in voxels (in the caudate) that are outside of the mask I used as a pre-threshold mask. I'm not sure how to interpret this as I thought using the pre-threshold mask would only yield results within the mask?


Thank you in advance for your insights.


Kind regards,

Lucia

Hello,
           The "Pre-threshold masking" option in the Post-stats tab should do this,

I have a very specific hypothesis about how the activation within the PCC will change in the 3 conditions. Is there a way (either via the GUI or via scripting) to apply a mask so that the FEAT analysis only occurs within this region (rather than across the whole brain)?
