One goal of synthetic biology is to understand the exciting biological phenomenon by reconstructing the systems that have the similar behavior to native. The design process is always very difficult for the biologists as the only information is the desired phenotype. Even the general system are improved to meet the requirement, the choices of reactors and the stability of the system are still problems for the experimentalists. Here we are trying to use the computer instead of the human brain to do the design process.

Goal
The ultimate goal of our program is to assist the experimentalists to design the plasmid that works as the requirement. For example, if an oscillator behavior is the requirement as the input of the software, then the output in our imagination is a DNA sequence which works as an oscillator in E.coli or other specific biology. It is only an imagination that we have a long way to go. So, as the first goal, the output we are trying to do for the software is a network which can stably work as the requirement. Generally, the desired phenotype is the input of the software, and, optionally, the restrictions extracted from the other experiments or from the condition can be the input at the same time. And the output is a list of networks that have the similar phenotypes to the requirement, with the information of the value of parameters and the sensitivities.
Work Flow
The flow chart is shown in Figure1. The three-layer optimization is expected during the whole design process: the optimization of parameters in a fixed mathematic model, the selection of interaction forms in a fixed topology and the comparison and screening of different topologies. And during the optimization of the parameters, there are two score functions considered. One is the RMSD(root mean square deviation) between the phenotype of the designed network and the requirement, and the other is the sensitivity of each parameter. As the cell system is noisy, the networks are hard to realize in experiments if some parameters are too sensitive. So the parameters' sensitivities are working as a filter to get rid of the networks that works not stably enough. After the three-layer's optimization and comparison, the list of the best networks are output as the final results.
INTERFACE
A user-friendly man-machine interface is realized in our software with C# for the experimentalists.The interface is shown in Figure2.Users can input the requirement curves with uploading a data file. And the picture files for curves are also supported by our software.
