Dear Afni community,

I have been trying to run an analysis in these last few days in which I have an AM1 regressor treated as being part of the baseline model via the -stim_base option in 3dDeconvolve. My understanding is that only AM1 and AM2 regressors can use the dmUBLOCK and dmBLOCK basis functions. Is this correct?

Here is the error I am getting:
** ERROR: '-stim_base 1' illegal with '-stim_times_AM1'
** FATAL ERROR: Can't continue after above problems!
My understanding is that 3dDeconvolve is telling that amplitude modulated/duration modulated regressors can't be treated as being part of the baseline model. Is this correct? And if so, why not?

Thank you,
Best regards,

Ruy
