Dear Tobias: The SPM.mat files from SPM99 and SPM2 share only their name in common. The internals of the file are entirely different. SPM2 also has no facility for using the old SPM_fMRIDesMtx.mat files (which I also thought were convenient for repeating analyses). The bottom line is you have to setup the analyses fresh for spm2, and you will have to setup the analyses new each time. There is no template-type function in spm2. There have been a number of messages on the list regarding batching and automation of these issues.
