| Abstract: | This paper studies the protein sequence filtering algorithms, and proposes a protein sequence filtering algorithm based on the hidden Markov Models according to the large numbers of redundant sequences in the protein database. It also specifies the method of building the hidden Markov Models in the protein database and the main formulas of solving and estimating to the major parameters in the model. Moreover, some tests for sequence filtering algorithm has been conducted by using the models created before, and the testing results show that the homologous protein sequence filtered by the algorithm proposed by this paper can achieve to an accuracy degree of more than 95%. |
