Existing research mainly focuses on the specific steps of the algorithm or is for specific problems, lack of high-level abstract domain algorithm framework. Multiple sequence alignment algorithms are more complex, redundant and difficult to understand, and it is not easy for users to select the appropriate algorithm, as a result some computing errors may be caused. Based on our constructed pairwise sequence alignment algorithm component library and the convenient software platform PAR, a few expansion domain components are developed for multiple sequence alignment application domain, and specific multiple sequence alignment algorithm can be designed and its corresponding program, i.e., C++/Java/Python program, can be generated efficiently, thus enables the improvement of the development efficiency of complex algorithms as well as accuracy of sequence alignment calculation. A star alignment algorithm is designed and generated to demonstrate the development process.
