Hello AFNI team,

I am following the instructions here to complete a gPPI analysis: https://afni.nimh.nih.gov/CD-CorrAna

In Step 3 it recommends plotting the deconvolved seed timeseries to see if it looks reasonable when comparing to the stimulus presentation in the experiment. The data I am analyzing is a fast, event-related design, therefore I am wondering how to validate this step? I have used 1dplot to look at the timeseries before and after deconvolution, although I am not sure how to evaluate these plots.

In addition, for step 6 when running the regression, do I include all of my conditions of interest into one 3dDeconvolve step? For example, my code is pasted below with four conditions of interest (hour, day, week, month). Or should I run 3dDeconvolve four separate times instead, one for each condition?

Thank you,
Catherine
