More information about "motions"

Hello,
Would it possible to have more information about the "motions" measures? Indeed, it doesn't seem to be a parcellation technique as described in the project documentation.

Hi,

the motion parameters were probably obtained during the realignment-step in the preprocessing of the fMRI data. Basically they are translations (x,y,z axis, usually columns 1-3) and rotations (around the axis, columns 5-6), which were used to correct the images for the participant's head movements.

Best,
Simon

Simon is right :)
