Re: [NMusers] cumulative AUC

From: Leonid Gibiansky <lgibiansky_at_quantpharm.com>

Negative CMT (in the data set) resets compartment amounts (CMT=-4 in
this case)
EVID = 4 resets all system, including A(4) (if washout time was long
and all compartments can be set to 0)
Also, it is easy to do post-processing, subtracting Cycle 1 AUC from
Cycle 1-2 AUC to get Cycle 2 AUC, etc.
Hope this helps
Leonid
