I have run several TBSS analysis on FA data, and I have used randomise option to perform two sample t-tests.  Now, I would like to determine which tracts show a statistically significant difference between the groups.  

For this, I have created a mask image using the tbss_tfce_corrp_tstat result  image, everything that is above 0.95 there is a 1.  Then, I multiplied this mask by the JHU-ICBM-T2-1mm.nii.gz atlas to get the list of tracts.  

However, when I checked the results there are other regions/tracts that shows statistically significant differences between the groups but are not part of this atlas.

Is it okay to use the atlas JHU-ICBM-tracts-maxprob-thr0-1mm to find the labels that are not included in the JHU-ICBM-T2-1mm.nii.gz atlas?

If so, where I can find the list of white matter tract labels?

I would appreciate any help.

Thanks,

Bedda
