Hi Tyler, <div><br></div><div>I'm not sure this is exactly what you want to do, but the simplest thing is to create a mask image from the tracks and read the FA values within the mask. A command for this might look like:</div>
<div><br></div><div>$ tracks2prob yourtracks.tck -template fa.mif - | threshold - -abs 5 - | mrstats fa.mif -mask -<br><br>This will give you the average FA within those voxels that have been visitied by more than 5 tracks.</div>
<div><br></div><div>Cheers,</div><div><br>Donald.</div><div><br><br><br><div class="gmail_quote">On 6 June 2012 09:20, Tyler Rickards <span dir="ltr"><<a href="mailto:tyler.rickards@gmail.com" target="_blank">tyler.rickards@gmail.com</a>></span> wrote:<br>

We have used other imaging methods in the past and like this technique very much, but after we create the .tck files, how do we get the underlying FA value of the tracks we have isolated? I don't see any options in the GUI and I am unaware of the commands necessary for getting FA of the tracks we are considering.</div>
<div>Could you shed some light on this? Is there a simple command I'm missing?<br>Thank you.</div></div><span class="HOEnZb"><font color="#888888"><div>Tyler.</div>-- <br>Graduate Student <br>Medical/Clinical Psychology Program <br>
