Dear SPMers Needs help regarding BMA, I would like to retrieved the mean values from Region A to region B In the manual pg 335 under 34.3.4 Summary Statistics and Group Analyses, I've tried using command for for i=1:6, b(i)=BMS.DCM.rfx.bma.Eps(i).B(4,1,1); end ??? Reference to non-existent field 'Eps'. I've checked the .bma parameters only have .mEp .sEp .mEps and .sEps Thanks in advanced
