I would like to smooth a dataset with different FWHM values for x,y,z. say 2mm in x, 3mm in y etc.
Unfortunately I could not find a way to enter more than one number in 3dmerge or 3dBlurToFWHM. Forum search revealed a tool called 3dnonisosmooth, but it does not seem to allow this either, at least the help does not say how to enter FWHM values as parameters...
Am I missing something, or is there a workaround?
