Original Abstract

Nowadays, next-generation sequencing is on the rise as a cost of sequencing is constantly dropping. However, the processing of the sequence data remains problematic as the algorithms for reference-based assembly are both computationally and time-demanding. Moreover, resulting assembly is still imperfect. In this paper, we present a new method for improving the quality of the consensus sequence from the assembled data. We examine the regions in the consensus sequence, which show a high number of ambiguous nucleotides. Using a classification of reads covering these regions, we try to reduce the number of ambiguous nucleotides in the consensus. This improved consensus sequence then can be used for bacteria typing and precise discrimination of bacteria strains.
