<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>Hey DTI Studio experts!!!<br>
<br>
So in my project I'm tracking 3 frontal-striatal white matter tracts, and also
track the CST. Our population is patients with Multiple Sclerosis.
One of our patients has such bad damage that there are no fibers that make it
through the CST ROIS. This is obviously important to include in the
analysis. BUT. When I go to save the file, it will not let me save
an empty file.<br>
<br>
So what do I do?<br>
<br>
To clarify what I'm doing:<br>
DTISTUDIO:<br>
Fiber Tracking<br>
Create 3 ROIS to define CST<br>
Save fibers: as binary images, as both a .dat file and a .bin file.<br>
<br>
Now I haven't had this issue with any other subjects (they've all had
fibers). Does any one know how to just make an empty .dat or .bin file
that is the same dimensions?<br>
<br>
<br>
Thanks<br>
<br>
