Hi TBSS experts,
I used TBSS to analysize my DTI data and got TBSS stat. results. Right now I'd like to
present or extract FA values in a standard space (say MNI 152) with a .txt or excel file
and correlate FA values with behavioral results. But I do not how to do this.
I tried to do that based on Gwenaelle's suggestion. S/he told me I can run the following
1) fslmaths my_tbss_results_corrp.nii.gz -thr 0.95 -bin my_significant_results_mask
2) fslmeants -i all_FA_skeletonised -m my_significant_results_mask -o
After I run these two scripts, I got 2 files: my_significant_results_mask. nii.gz and my_significant_results. txt.
In the .txt file, when I run my tbss__results_corrp.nii.gz, the .txt file shows six 0s in a
column; and when I run my tbss_results.nii.gz, the .txt file shows six numerical values
ranged from .4000 to .7000. So I guess they are FA values that I expect, but there are
no standard coordinates.
Can anyone tell me how to know the standard coordinate corresponding a specific FA
value? Ideally, I'd like to know the FA values and corresponding standard coordinates
from two groups of our subjects. Thank you!
