Hello FSL experts,
I am relatively new to using TBSS, so I'm not sure if I set up my model correctly nor how to interpret the results.
I have a single group of 25 participants, each with several biomarkers as covariates. In the GLM model, I detrended the covariates in matlab and pasted them in the GLM as EVs as well as set up contrasts each covariate. I ran randomise with 500 permutations off of that design.fsf file and got tbss_tfce_corrp_tstat*.nii.gz images for each covariate. When I load those images into fsleyes thresholded at 0.95 - 1, I have several images that show significant voxels.
If my model is set up correctly, what do these results mean in terms of fractional anisotropy and the covariates?
Apologies if this is a very trivial question.
Thank you so much!
Erin
