Greetings,

This is my first time running the simple coorelation as instructed here: [afni.nimh.nih.gov].

I had a few questions:

1. 3dSynthesize -cbucket CbucketFileFrom3dDeconvolve+orig -matrix x1DFrom3dDeconvolve -select ... prefix EffectsOfNoInterest

How do I go about selecting the correct options for -select...? In a search I noticed most people used -select polort.

2. 3dcalc -a Corr_subj01+tlrc'[SubbrickForR2]' -b Corr_subj01+tlrc'[SubbrickForBeta]'-expr "'ispositive(b)*sqrt(a)-isnegative(b)*sqrt(a)'-prefix Corr_subj01R

Which R^2 value do I want to use from 3dDeconvolve? I have the Full R^2 (assuming this is the one I want to use), the Global R^2, and the Seed R^2. The same question again, but this time for Coefficent?

Thank you for your guidance. Much Appreciated.
