Hi all, <br>
<br>
I have some questions regarding the parameters of streamtrack:<br>
<ol>
<li>Should it basically be the same to use a 0.2 thresholded FA
image as -mask input as to apply a -cutoff 0.2? Because it is
not. There seem to be fibers present in low FA regions if I use
the -cutoff parameter. It does change something, but I am not
sure what exactly :)</li>
<li>How is the -num parameter applied internally? Don't you just
seed in every voxel of the mask image? <br>
</li>
<li>If I use the probabilistic version, how many times is the
trajectory originating from one seed point sampled and how is
the result combined into one final fiber?</li>
</ol>
<p>Thanks in advance!<br>
</p>
<p>Peter<br>
