Hi SPM list,
I made this question some time ago but still didn't get a response.
I want to leave out some of the trials in a parametric modulation
regressor. Is there a way to do this?
I would have thought to put "0" in the modulation of those trials but
it doesn't seem clever if the other values are "1", "2", "3", "4". It
may take the zero and use it in the modulation as simply less then
one.
Any clue please?
