Thank you Donna! I now get good mapping on right hemisphere, as it provides AFM and MFM, however, the corresponding left hemisphere atlas file for SPM5 space always only have 1 coordinate files, and it doesn't give me AFM and MFM, seems it only gives AFM, which is just not showing the clusters that I can see in MFM. No matter which spec file I opened right now, somehow mapping to SPM5 left and right atlas would give me different available coordinates (which is fine as I can open new coord after the mapping is done), but the metric seems only allow me to write one (MFM) for left atlas..
Sorry for keep on asking you all these questions, hopefully this is it! :) Thanks!
