DSAS program

We have developed a new program, DSAS, based on the modified phase-retrieval algorithm to determine the anomalous scattering substructure. In the DSAS, we developed an automated parameters setting method that can automatically solve the optimal algorithm parameters for different SAD data sets. The program has a user-friendly graphical user interface (GUI), where users only need to input experimental information, and the determination of substructure solution can be automatically completed. Meanwhile, the iterative process can also be real-time monitored through the GUI, which greatly reduces the difficulty of use for users.
