	usage: __main__.py [-h] [--length_weighting] [--reference REFERENCE]
	                   [--sh_basis {descoteaux07,tournier07,descoteaux07_legacy,tournier07_legacy}]
	                   [-v [{DEBUG,INFO,WARNING,ERROR}]] [-f]
	                   in_bundle in_fodf afd_mean_map
	
	Compute the mean Apparent Fiber Density (AFD) and mean Radial fODF (radfODF)
	maps along a bundle.
	
	This is the "real" fixel-based fODF amplitude along every streamline
	of the bundle provided, averaged at every voxel.
	
	Please use a bundle file rather than a whole tractogram.

	  -v [{DEBUG,INFO,WARNING,ERROR}]
	                        Produces verbose output depending on the provided level. 
	                        Default level is warning, default when using -v is info.
	  -f                    Force overwriting of the output files.
