Dear FSL group,
I used the probtrackx2 routine to perform fiber tracking with activated regions found in GLM analysis as seeds. Thus I got one tracking result for each seed of each subject, and the tracking results was automatically converted to the standard MNI space since the seed masks were extracted in the standard MNI space. I just want to present the group fiber tracking results of each seed and infer their separate role in my study. However, I'm not sure how to perform the group analysis using the individual results. For example, could I choose a threshold for individual results (e.g., 2500, half of my stream lines) and then set a group threshold (e.g., 0.9, this voxel/fiber was found in at least 90% of all the subjects)? Any suggestion would be appreciated. Thank you very much.
Best regards,
Bingjiang Lyu
