Hello,

I have several questions regarding the dwi.ecclog file data from Tracula, using the FreeSurfer version V6.0.0.

1) Does Tracula still use eddy_correct from FSL, or was it updated with the new eddy function from FSL?

2) Are the values for each slice of dwi.ecclog relative to the first slice or to the previous slice, or to another template? is it the same for both rotation and translation values?

3) What is the coordinate system for the rotation values? Is there a way to determine the total rotation from these 9 values?

Thanks,

Sincerely,

Loic Daumail
