Hi AFNI gurus,

I'm using the command 3dUndump to create a 6mm sphere ROI around a xyz coord I choose. When I do this all my ROIs have the same number of voxels and same radius, yay. However, when I resample to the EPI dataset so that I can run a correlation analysis, it outputs ROIs with different numbers of voxels. Why is that? How do I make sure all my ROIs have the same number of voxels after resampling?


Also, what is the best way to deal with overlapping ROIs in 3dNetCorr?

Thanks!!
