The assignment of cell cycle by tricycle

[seven1112233]

Hi,

Tricycle is a useful tool to predict the cell cycle. When approximately relating 0.5pi to the start of the S stage, pi to be the start of the G2M stage, 1.5pi to the middle of the M stage, and 1.75pi-0.25pi to the G1/G0 stage, how do we define the remaining region from 0.25pi to 0.5pi ? Would it be possible for me to define this specific region as the G1-S stage?
