Dear Experts, On the following web page http://imaging.mrc-cbu.cam.ac.uk/imaging/MaskedEpiNormalization, we found an instruction how to do a Masking procedure for EPI normalization. However, we noticed that the instruction is obviously written for SPM99 because we cannot follow the instruction since SPM2 is asking for something else (weighting template when registering?. weighting source images when registering..etc.). I would greatly appreciate your help. Maybe you can give me the correct instructions for SPM2 in order to do the masking for the EPI normalization. Thank you very much in advance.
