Description of corrective post-processing

Postprocess	Purpose
Wake vs. Sleep	Increase sensitivity to wake states by combining the probability of Active and Quiet Wake to determine wake vs. sleep, then determining most probable wake state.
Wake to REM	Ablate REM episode when an invalid Wake to REM transition occurs.
End of REM	End a REM episode if the probability of REM declines past a moving average.
Minimum REM Duration	Force REM episodes to be a minimum duration via a backwards pass.
Valid Transitions	Repair a sequence of states to the most probable physiologically possible sequence of states (Fig. 6).
