Dear experts,
<div><br></div><div>I'd like to ask what could be the reasons whay csdeconv fails and gives an error like </div><div><br></div><div><div>> csdeconv data.mif response.txt -mask mask.nii -grad gradtable.txt CSDm.mif</div>
<div>csdeconv: performing constrained spherical deconvolution... 0%csdeconv: failed to converge</div><div>csdeconv: failed to converge</div><div>csdeconv: failed to converge</div><div>csdeconv: failed to converge</div>
<div>
csdeconv: failed to converge</div></div><div>csdeconv: failed to converge</div><div>csdeconv: failed to converge</div><div>etc.</div><div><br></div><div>I tried with different -lmax and with different thresholded sf.mif (values 0.7, 0.6, 0.5, 0.4).</div>
<div><br></div><div>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?).</div><div>How should I proceed best in order to debug?</div>
<div><br></div><div>Thanks in advance!</div><div>Markus</div>
