Dear AFNI experts,
I am currently trying to perform a gPPI analysis, but I’m not quite sure about how to apply the “upsampling” from step 2.
As an example, I have a TR=2s, 196 volumes, my stimulus onsets look like [13.938 113.938 159.938…], and stimulus duration is fixed at 0.3s. So how should I fix the sub_TR ?
Thank you very much in advance,
