hi-I am trying to define the contrast using SPM jobs for the several
repeated runs at the same times. it seems that SPM doesn't taking into
consideration the user specified regressors, and thus totally messed up
the contrast. for example, if I have three runs, each has 4 conditions
and 6 user specified regressors (motion parameters). the contrast for
the first run , say [1 0 0 0] is correct. For the second run, the
contrast is defined as [0 0 0 0 1 0 0 0] by SPM, but actually should be
[0 0 0 0 0 0 0 0 0 0 1 0 0 0]. I wonder if anyone has came up with the
same question and has a solution.
thanks,
gui
