Dear SPMers, We would like to extract the activation clusters for each subject in its own native space. I need to transform back the activation clusters from MNI to native space. I tried using the deformation batch but I'm not sure which images to use in "Apply to", the originally normalized images? For the parameter file I should use the seg_inv_sn file right? Should I keep the default parameters for bounding box and voxel size? I added the screen shot of the batch to make myself more clear, Best Regards, -- *Marine*
