Hello all,
I have finished TBSS pipeline according to user guide ,and got some significant regions .However , I still have the following questions to ask for help .
Before that I am sorry about my poor English .
1. Which atlases of FSL correspond to JHU-ICBM-DTI-81 White Matter and Juelich Histological atlases ,which were used to label clusters with significant FA alterations .
2. How to extract the FA value of every subject and average FA value of per group , and then plot something similar to figure 1?
3. How significant difference regions can be made into ROIs , and these ROI can be applied to every subjects ? or say how to implement a ROI-based TBSS?
4. Could TBSS make analysis with some covariants(e.g. age,weight)? If so ,please tell me way because I just make simple analysis whitout any covariant following user guide .
5. Could TBSS conduct correlation analysis between FA and covariants(e.g. age,weight) ,and get correlation coefficient r and P ,as shown in figure 3 ?
Best regards.
Xin-Fa Shi.
