Hi experts,

I am new to AFNI and could use a bit of help. I am interested in examining how my variables of interest relate to amygdala resting-state connectivity. I am using preprocessed normalized resting-state fmri data.

In order to calculate amygdala connectivity maps, I have ran 3dTcorr1d on my preprocessed individual datasets. I have then used 3dMVM to assess the associations between my variables of interest and amygdala connectivity at the group level. I would now like to perform cluster correction on my group level results, but am not sure how to go about this. If I'm correct, both 3dTcorr1d and 3dMVM do not output residuals, which would be necessary to run 3dFWHMx to acquire the ACF model parameters. Or am I missing something? Should I choose different programs?

Any guidance would be much appreciated!

Thank you in advance.

Sandra
