Abstract
A new approach towards computing the periodicity transform of DNA sequences is proposed. The approach is based on the mapping of DNA symbols to pure quaternions. The resulting quaternionic periodicity transform outperforms the previously proposed complex periodicity transform due to enhanced, symbol-balanced sensitivity to DNA patterns. The theoretical finding is supported by a performance comparison of the two transforms and by an application example.
