Smooth ReHo?

Dear experts,

I saw the option, 'smooth ReHo' in DPARSFA menu.

I read a reference about ReHo analysis, the paper said that it should be smoothed after ReHo.

Is the option for later smoothing after ReHo analysis?

In addition if I selected that option, how about another processing including ALFF, fALFF, VMHC etc?

Are the results of those analysis except ReHo smoothed after, before or none?

I just want to make all kinds of analysis at once.

Does the smoothing process apply to all kinds of analysis identically?

I found another option, 'Smooth FWHM [4 4 4]' above the 'smooth ReHo'.

Is the option for all functional data or anatomical data?

Best regards,

Saske
