Aser, If you you put your custom sequence into SPM, you can get the graphs above. The key variables are: SPM.Sess.U.u, time variable is 0:TR/#oftimebins:TR/#oftimebins*size(SPM.Sess.U.u,1) SPM.xX.X, time variable is 0:TR:TR*size(SPM.xX.X,1), this is the convolved data., this is the stick function or stimulus on times
** Sess will need to be index for each run (e.g. Sess(1).U) ** U will need to be indexed for each condition (e.g. U(1).u, U(2).u) Hope this helps. Best Regards, Donald McLaren ================= D.G.
