Hello,
I am carrying out an amplitude modulated analysis for one trial type and want to know what to do with the other trial type in my 3dDeconvolve call (see below).
Is it correct to simply use the -stim_times option to code for this stimulus-of-no-interest so that it will not be considered part of the baseline? In the file (below) this is the 'Facts' condition.
My second question is whether or not I have used the BLOCK function correctly so that it knows that my stimuli lasted for a duration of 16 seconds.
This is the first time I am doing an AM analysis. Please let me know if my 3dDeconvolve call looks strange for any reason.
Thank you,
Christine
