Hey all,

I was wondering if someone may be able to help a college senior out with his senior research project. I'm using SBML to model one of my advisor's models on oxygen kinetics.

I've almost completed the model itself, but the last thing needed was to implement the events structure. I wanted to know if there was a way to make it so that, for example, the lag phase event assignment is a constant value, but after the lag phase the second event/assignment was a function of time.

To date, this is what I have done. Within a 15-minute window:

First event: Steady state warmup event
for t <= tw = 3 minutes the event assignment is Qm = constant value.

Second event: Reaching steady State
for t > 3 minutes the event assignment is Qm = QWm + dQ*exp((tw-time)/Qc) (QWm, dQ, tw, and Qc are constants).

How can this be done?
