[Mrtrix-discussion] streamtrack SD_PROB

[Luke Bloy]

Hi,

I'd like to get some more information about the method that you use for 
your probabilistic tracking using the fods, specifically what it means 
to use an inclusion/exclusion roi.

1) the progress bar for streamtrack is generally something like this 'N 
generated,      X selected', what does this mean? what is the selection 
criteria, I get this message even if no inclusion or exclusion rois are set.

2) Lets say that I set an inclusion roi, is the process to generate 
fibers, until enough get to the inclusion roi? if so it seems as given 
enough time I'd be able to fiber track anywhere to anywhere. Am i 
missing something?

3) Is there anyway to generate confidence intervals on the fibers that 
are generated? If I'm using an exclusion or inclusion roi, I'd like to 
have an idea with how likely a fiber is to.

thanks,
Luke
