- Subject: [SCIRUN-USERS] BioTensor Power App questions
- Date: Fri, 15 Jul 2005 13:59:05 -0400
Hello,
I was wondering if any of you have used the BioTensor Power App? I had
a couple of questions regarding its use for fiber tracking within DTI
images.
1. I have a raw DTI dataset in a 3D matrix form which contains a 3x3
tensor at each element within the matrix. I can also change the tensors
at each element to be 1x9 instead of 3x3 using MATLAB if necessary. I
was wondering how I can import that into a tensor volume or nrrd dataset
that can be read by BioTensor?
2. The example DTI data demo-DWI.nrrd that's given within the SCIRun
datasets brain-dt has four dimensions. The first dimension is 12,
whereas the other three dimensions correspond to the size of the
dataset. What does that first dimension mean physically? Should my
dataset have the same size first dimension?
Thanks in advance for your help!
