Hi George,

The errts dataset is the noise from a task-based first
level regression, and nothing special is changed that
way for resting state data (I guess that is what you have).
But for rest it is not clear what you would otherwise use
as noise terms, the non-drift regressors of no interest?

In any case, this method should still provide a reasonable
idea regarding data quality, which is the purpose.
