Looking at the equations in the papers we can't find any function which would
cause the models to loop. Indeed, even where we have access to the author's
original XPP code, we are struggling to find the "loop function" (although, we
confess this may be due to our misinterpretation of the XPP!).
In SBML is it possible that an event is used to get the model to repeat? (My
apologies for my ignorance here!).
Indeed, the events are responsible of the cycling. For Novak and Tyson
1997, they are described in Table 1, in the section "switches". There are
two events:
S-Phase Start
=============
When SPF becomes superior or equal to 0.1
after 60 seconds kp = kp / 2
Cell division
=============
When UbE becomes inferior or equal to 0.1
immediately kp = 2 * kp
Mass = Mass / 2
