Dear AFNI expert:

I want to estimate the smoothness of a single volume (with structure).

3dFWHMx seems to get me a reasonable result. According to the 3dFWHMx help manual, I tried with and without the "-2difMAD' option as below. The results are the same. Could you please suggest me the appropriate steps?

Thank you.

David
