Hi Anastasia Thanks a lot for your very nice talk today. I would have another question on top of the one below. I have looked at the formula to calculate the total motion index, and for the third motion parameter (percentage of slice with signal drop-out), all subjects except 2 had a 0 value. So in the formula, I would not be able to calculate the motion factor for this parameter because median, upper and lower quartile are all 0, is that correct (it would make (x-0/0-0))? Thanks for your help Celine
