[Mrtrix-discussion] csdeconv: failed to converge

[Markus Gschwind]

Dear experts,

I'd like to ask what could be the reasons whay csdeconv fails and gives an
error like

> csdeconv data.mif response.txt -mask mask.nii -grad gradtable.txt CSDm.mif
csdeconv: performing constrained spherical deconvolution...   0%csdeconv:
failed to converge
csdeconv: failed to converge
csdeconv: failed to converge
csdeconv: failed to converge
csdeconv: failed to converge
csdeconv: failed to converge
csdeconv: failed to converge
etc.

I tried with different -lmax and with different thresholded sf.mif (values
0.7, 0.6, 0.5, 0.4).

Principally the commands are correct as they worked with other brains, but
not with the one in question ( a lesioned one does it not work with brain
lesions?).
How should I proceed best  in order to debug?

Thanks in advance!
Markus
