Hi everyone,

I am trying to use the ClipFieldToFieldorWidget module to extract the Diffusion Tensor Imaging data from just one part of the brain (the left Thalamus) .  I have .fld files of both the Thalamus and the DTI (they should already be aligned--they come from the same patient). I'd like to export this clipped DTI data as a matrix in Matlab, and I'd be interested in seeing what a .fld file looks like in Matlab also.  After playing around a little, I realized that ClipFieldToFieldorWidget returns an error without converting the DTI Field to an Unstructured Mesh first--the Left Thalamus Field is already an unstructured mesh.  As you can see, converting the clipped field to a Nrrd and then to a Matrix didn't work out. I end up with a MATLAB file that is unable to load, which is especially confusing as there are no errors in exporting the clipped field to MATLAB.  If anyone has any ideas about what I can do to make this code work I'd appreciate it!

Best,
