Fig. 2From: ASAP 2: a pipeline and web server to analyze marker gene amplicon sequencing data automatically and consistentlyA sequence quality profile demonstrating how ASAP 2 selects the high-quality region for further processing. The original quality score at each position is converted into a moving average score to reduce the volatility caused by occasional drop of score (e.g. at 108) due to sudden quality changes at certain regions. The optimal high-quality region (1–143) is then selected by the pipelineBack to article page
