Developed a robust structure factors pipeline for the cctbx/cctbx_project repository, focusing on maintainability and configurability within scientific computing workflows. Leveraging Python and C++ via Python bindings, the work introduced a modular algorithm framework supporting direct, FFT, and TAAM pathways, with conditional TAAM integration based on dependency checks. The implementation enabled flexible configuration through extra parameters and improved code organization by refactoring algorithm selection and removing legacy components. Emphasis on code refactoring and modernization streamlined future enhancements, reduced runtime risks, and facilitated easier maintenance, while supporting evolving pydiscamb usage and ensuring accurate structure factor calculations in crystallography applications.
