<p class="MsoNormal">Dear camino expert, <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am trying to select a fewer number of gradient directions (let’s say 60) from a sequence of 210 gradients (it’s a three-shell sequence) in such a way that all the gradients/points of the subset are equally distributed on the sphere. I
came across the function ‘subsetpoints/subsetscheme’ of camino, which seems to do the job.
<o:p></o:p></p>
<p class="MsoNormal">Should the b0s (b=5 in my data) stay or be removed before entering subsetpoints?
<o:p></o:p></p>
<p class="MsoNormal">Also, when I try running the second step (subsetscheme), get the following error. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">subsetscheme -schemefile 198_PA.scheme -imagelist 198_PA.nii -subsetpoints elec198_best40.points -outputroot subset<o:p></o:p></p>
