Hello AFNI experts,
In our design, resting state scans were acquired from subjects at 2 time points. Behavioral data was also acquired at each time point. We would like to use both sets of behavioral data as a covariate. Is this possible with 3dGroupInCorr?
When using the "-paired" option, does 3dGroupInCorr subtract the two sets of 3Dcorrelation maps and then performs a one-sample t-test as noted in usage description? If this is the case, would it be appropriate to subtract our behavioral measures at the two different time points and use the subtracted values as a covariate?
