Dear DCMers, I am also going through the SPM8 manual and am also getting surprised at exactly the same stage: "compare DCM models", but for a different reason: Instead of the prompt: "Number of models to compare" this facility opens a batch editor called : "MS.DCM" Actually a "Thank you" message also appears on a DCM menu tab, but I don't get any error message in Matlab. What is going wrong? Many thanks in advance, Iwo From: SPM (Statistical Parametric Mapping) [mailto:[log in to unmask]] On Behalf Of shaza zaghlool Sent: 23 March 2011 18:06 To: [log in to unmask] Subject: [SPM] comparing DCM models Hi I'm trying to reproduce the results in the SPM manual in section "32.3.4 Comparing models" For some reason when I press the "DCM" button and then Choose Compare, I don't get prompted to enter "Number of models to compare". I get a "Thank you" instead. In the matlab command window it says "Please refer to this version as DCM10 in papers and publications. SPM8: spm_api_bmc Any idea what the problem could be here?
