[Mristudio-users] When Fibers Aren't there

[susumu]

Hi Meg,

 

I've been thinking how we can do this but could not come up with a way with
our programs.

I think you need to create one using Matlab or IDL, which requires only one
line.

Subject: [Mristudio-users] When Fibers Aren't there

 

Hey DTI Studio experts!!!

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.

So what do I do?

To clarify what I'm doing:
DTISTUDIO:
Fiber Tracking
Create 3 ROIS to define CST
Save fibers: as binary images, as both a .dat file and a .bin file.

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?


Thanks

Meg
