Hi everyone, I'm in my first year PhD and I try to use the DEM part of SPM to model comportment. I want to use the spm_MDP_DEM function in order to make a hierarchy of POMDP, however their is no much documentation on this function (but the comment in the code). I would like to know what should be put inside a DEM structure and what what could be put inside. If you have some documentation other example that those in the toolbox or advise i would be glad, Many thanks, -- RĂ©mi PHILIPPE 06 88 81 49 01
