[Camino-users] error with subsetscheme

[Versace, Amelia]

Dear camino expert,

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.
Should the b0s (b=5 in my data) stay or be removed before entering subsetpoints?
Also, when I try running the second step (subsetscheme),  get the following error.

subsetscheme -schemefile 198_PA.scheme -imagelist 198_PA.nii -subsetpoints elec198_best40.points -outputroot subset
Exception in thread "main" java.util.NoSuchElementException
        at java.util.Scanner.throwFor(Scanner.java:862)

        at java.util.Scanner.nextInt(Scanner.java:2117)
        at java.util.Scanner.nextInt(Scanner.java:2076)
        at apps.SubsetScheme.execute(SubsetScheme.java:109)
        at apps.EntryPoint.main(EntryPoint.java:290)

Any help will be greatly appreciated!
Thanks, Amelia
