I need to do regression analysis (the independent variables in the regression
are independent variables in the experiment design). I heard that it should use
the "parametric modulations", as highlighted in the attached picture, right?
(pls check the highlight in the attached picture, thanks!) After implementing
the parametric analysis, there will be no contrast in the contrast window. how
to define the contrast (pls very specially)? could you also tell me which file(s)
on internet (preferably on www.fil.ion.ucl.ac.uk/spm) or which book(s) do
address exactly this point (I cannot find this point in SPM8 manual.)
Looking forward to your reply. Thank you very much!
