[Mristudio-users] problem opening .d file in Landmarker

[susumu]

Hi julie,

The tensor file has to be opened using a dedicated button saying "open .d".
You can't open them from the regular "open" icon. This is because Landmarker
needs to know when a tensor file is loaded so that it can do proper
reorientation calculation for the tensor.

The tensor file should be 6xdimension 1xdimension 2xdimension 3, if you save
them correctly by DtiStudio, meaning dxx, dyy, dzz, dxy, dxz, dyz are stored
in one file.

The trace image should look like a brain. You see white lines across a
background when the matrix size is not properly set. You could email me the
trace file if you want me to check.

Please let me know if you have further question.

Susumu

Subject: [Mristudio-users] problem opening .d file in Landmarker

I have processed 2 DTI scans using DtiStudio, saving all output files
accordingly. I am now attempting to normalize the iso-image (mean of DWI's)
to the ICBM-MNI-DWI template using Landmarker. I am able to open the
iso-image and load the FA, b0, eigenvalues, and trace files (are they
supposed to look like anything, because mine just look like white lines
across a black background?). Anyway, when I try to open the tensor (.d)
file, I get an error message:

File size is smaller than expected value.

Does anyone know what I am doing wrong?

Thanks in advance-
