Hi Laura,
That is actually why both numbers are reported, they are usually different.
Censoring based on motion parameters (as opposed to base on outliers)
comes from an estimated changed in subject position between 2 time points.
But we cannot tell during which time point the motion occurred, possibly
during both. So by default, both time points are censored.
So if C time points are above the censor limit, censoring will be between
C (if C is zero, or C+1 if motion time points are contiguous) and 2C, if
none are adjacent.
