Construction of the converging tree up to the level containing the control node CHK1/2. The nodes Bcl2, Cytoc/APAF2, Caspase8 and Caspase9 in the simplified cancer cell signaling network are renamed as Bcl, CytocAPAF, Casp8 and Casp9 in the converging tree for simplicity. The converging tree is constructed up to the 4th level to find out a control node CHK1/2 (marked with a red ball). The number beside each control node denotes the state value of the node
