Background In modern paired-end sequencing protocols short DNA fragments lead to adapter-appended reads. Current paired-end adapter removal approaches trim adapter by scanning the fragment of adapter on the 3' end of the reads, which are not competent in some applications. Results Here, we propose a fast and highly accurate adapter-trimming algorithm, PEAT, designed specifically...
