Dear Lars, You can find the outputs here: https://mcgill-my.sharepoint.com/:f:/g/personal/caroline_landelle_mcgill_ca/EjVi1nZD-wJLka6piE_7z1EB-YNmNZVWqtZwUW4Iw0Djiw?e=ajDTwo it inlcudes the .mat output from Physio + the figures Thank you a lot for your help ! Best, Caroline

These parameters are mainly used to remove motion-related fluctuation in the signal. The intent is to identify the amount of motion in a specific volume, and thus the parameters should...

Ok I have done some tested. I think mean slice-wise magnitude is the best option. As you can see after the timeserie cleaning (3rd graph) it is really similar to...

Sorry for the lack of explanation: - motion_magn is the mean magnitude across slices (average of magnitude across all slices for each time point) - motion_x_mean is the current moco_params.tsv...

For the magnitude, I think the previous formula was ok sqrt(x*x+y*y) $$\sqrt { \sum_{slice=1}^n T_x[slice]^{2} + T_y[slice]^{2} }$$
