Hi Lars - This sounds like the subject was trying to climb out of the scanner: 3cm average translational motion and 24% of the slices in the series have drop-out. How do the images look?

HI, Is there a rule-of-thumb upper level of acceptable head motion? The tutorial gives these values as examples: AvgTranslation AvgRotation PercentBadSlices AvgDropoutScore 0.489419 0.00398925 0 1 I have a subject with AvgTranslation AvgRotation PercentBadSlices AvgDropoutScore 30.018 0.209 24 1.6 I plan, of course, to use the index described in Yendiki et al. (2013) but would such high levels nevertheless be considered disqualifying a priori? Thank you!
