[Mrtrix-discussion] SIFT: normalise to the b0 image

[Jan Schreiber]

Dear MRtrix Team,

thank you very much for this great software and for making it freely 
available!

In your publication "SIFT: Spherical-deconvolution informed filtering of 
tractograms" you state

"The diffusion signal must not be normalised to the b = 0 image 
intensity. This preserves the linearity of the spherical deconvolution 
transform between the measured DW signal and the resulting FOD."

Shouldn't we preserve the linearity of the spherical deconvolution 
transform between the FOD and the DW _signal attenuation_ rather than 
the DW _signal_?

Thanks,
Jan
