Dear FSL users,
I'm a beginner of TBSS(v1.2) and now planning to do correlation analysis
between FA values and clinical measurements (positive and negative
correlation) in the patients group. I learned how to do it from this year's
FSL mailing list, but I don't have enought confidence. Please check my method.
1. creating skeletons (mean_FA, all_FA, etc) with 5 patients.
2. creating desgin matrix and contrast using Glm window.
mEVsntag
Number of main EVs: 2
Number of additional, voxel-dependent EVs: 0
Group EV1 EV2
Input1 1 1 23
Input2 1 1 14
Input3 1 1 8
Input4 1 1 36
Input5 1 1 44
*The numbers in EV2 column are clinical mesurement.
mContrasts & F-testsntag
Contrasts: 2, F-test: 0,
Title EV1 EV2
C1 positive correlation 1 1
C2 negative correlation 1 -1
3. running randomise software
randomise -i all_FA_skeletonised -o tbss -m mean_FA_skeleton_mask -d
design.mat -t design.con -n 500 -D --T2 -V
Is it OK?
Sincerelly,
Takeshi Asami
