" **N.B.: This is also a required 'option'.\n"
" -FWHMdset d = Read in dataset 'd' and add the amount of smoothness\n"
" given at each voxel -- spatially variable blurring.\n"
" ** EXPERIMENTAL EXPERIMENTAL EXPERIMENTAL **\n"
" -mask mmm = Mask dataset, if desired. Blurring will\n"
" occur only within the mask. Voxels NOT in\n"
" the mask will be set to zero in the output.\n"
" -Mmask mmm = Multi-mask dataset -- each distinct nonzero\n"
" value in dataset 'mmm' will be treated as\n"
" a separate mask for blurring purposes.\n"
" **N.B.: 'mmm' must be byte- or short-valued!\n"
" -automask = Create an automask from the input dataset.\n"
" **N.B.: only 1 masking option can be used!\n"
" -preserve = Normally, voxels not in the mask will be\n"
" set to zero in the output. If you want the\n"

" -prefix ppp = Prefix for output dataset will be 'ppp'.\n"

" -quiet = Don't be verbose with the progress reports.\n"
" -float = Save dataset as floats, no matter what the\n"
" input data type is.\n"
" **N.B.: If the input dataset is unscaled shorts, then\n"
" the default is to save the output in short\n"
" format as well. In EVERY other case, the\n"
" program saves the output as floats. Thus,\n"

"-----\n"
" * If you don't provide a mask, then all voxels will be included\n"
" in the blurring. (But then why are you using this program?)\n"
" * Note that voxels inside the mask that are not contiguous with\n"
" any other voxels inside the mask will not be modified at all!\n"
" * Works iteratively, similarly to 3dBlurToFWHM, but without\n"
" the extensive overhead of monitoring the smoothness.\n"
" * But this program will be faster than 3dBlurToFWHM, and probably\n"
" slower than 3dmerge.\n"
" * Since the blurring is done iteratively, rather than all-at-once as\n"
" in 3dmerge, the results will be slightly different than 3dmerge's,\n"
" even if no mask is used here (3dmerge, of course, doesn't take a mask).\n"
" * If the original FWHM of the dataset was 'S' and you input a value\n"
" 'F' with the '-FWHM' option, then the output dataset's smoothness\n"
" will be about sqrt(S*S+F*F). The number of iterations will be\n"
" about (F*F/d*d) where d=grid spacing; this means that a large value\n"
" of F might take a lot of CPU time!\n"
" * The spatial smoothness of a 3D+time dataset can be estimated with a\n"

" 3dFWHMx -detrend -mask mmm+orig -input ddd+orig\n"
