Dear SPMers.
Excuse me for a stupid question. I have a problem with preprocessing in
"diffusion II" toolbox
Could you tell me how exactly it is needed to enter b-values and
gradients?
I have 84 dicom files getting from scaner (Siemens Magnetom Symphony 1.5
T) in 13 directions (b0 + 12 dwi). After the convertation process they
transform into 168(84 img + 84headers) files. What must I enter at the
"B values" and "Gradient directions" lines?
Is it ok:
- B values:
0 1000 1000 1000 1000 1000 1000 1000 1000 1000 1000 1000 1000
- Gradient directions:
0.000, 0.000, 0.000
1.000, 0.000, 0.500
0.000, 0.500, 1.000
0.500, 1.000, 0.000
1.000, 0.500, 0.000
0.000, 1.000, 0.500
0.500, 0.000, 1.000
1.000, 0.000, -0.500
0.000, -0.500, 1.000
-0.500, 1.000, 0.000
1.000, -0.500, 0.000
0.000, 1.000, -0.500
-0.500, 0.000, 1.000
Thank you beforehand...
