Hi Frank,

I hope this message finds you well. 

I'm currently working on saving the track files in MNI space and wanted to discuss my approach with you. So far, I've performed the fiber tracking within the subject's native space and saved the result tracts in MNI space. However, when I export the MATLAB file containing these tracts, it seems that the coordinates are not really in MNI space for each subjects.

Could you please share your thoughts on whether this methodology is appropriate? Additionally, I would greatly appreciate any suggestions or alternative strategies you might have for this process.

Best,
Tong

Hi Tong,

   Thank you for pointing that out. I will test it on my side (on my queue) and let you know.

Best,
Frank

Sorry about the issue.
Could you provide the steps to reproduce the issue?

I wanted to share some observations after reviewing the tracts in MNI space. I loaded several tract bundles to check their alignment with specific ROIs, using DSI Studio for visual confirmation.

It seems like there's still a mismatch; the tracts don't align with the ROIs as expected. Could you take another look at this? Thank you so much!
