Hi-

Are you using a version of AFNI from between 22 Feb 2013 through 20 Mar 2017?? Because if you are not, then this is not a problem-- that bug was fixed *long* ago. (And if you are reading that help message, then I don't think you have that old version of AFNI!)

You don't need to use MapIcosahedron to do this on your own-- I think you should just use "-NIFTI" or "-GNIFTI".
