Dear spm's users, When we specify the electromagnetic model, we need to choose a spatial forward(IMG, ECD, LFP) model for DCM. I have a question that whether this selection should be the same as that in 3D reconstruction>forward step. Or in other words, if I did 3D reconstruction in IMG forward model, then I should choose IMG spatial forward model for DCM? ĦĦĦĦAny help would be greatly appreciated! ĦĦĦĦBest regards! -- Haoran LI (MS) Brain Imaging Lab, Research Center for Learning Science, Southeast University 2 Si Pai Lou , Nanjing, 210096, P.R.China
