Hi,
I am just exploring AFNI as an alternative to SPM for resting state preprocessing, using the uber_subject.py and noticed that the estimates of head motion (saven in the motion_[...]_enorm file) is quite different from the framewise displacement calculated from spm motion parameters in matlab. Could someone clarify:

1) what exactly the difference is between FD and the motion estimate from afni (calculated with 1d_tool.py)
and
2) why this is used instead of FD for censoing.

Sorry if I overlooked a similar thread but I couldn't find the answer in the message board history.

Many thanks!
Janina
