  • Publication number: 20240013861
    Abstract: This disclosure provides an improved filtering techniques that can provide higher sequencing accuracy for processing high-throughput sequencing data. The filtering structure uses a hierarchical network structure comprising one or more network blocks for obtaining high quality sequences. Each network block comprises a base network module (or simply a base network) and a sequence filter. The base network generates one or more sequencing quality indicators. The sequencing quality indicators can represent qualities of accuracy of the basecalling of individual bases in a sequence, the quality of one or more sequences individually, or the quality of a group of sequences as a whole. The sequence filter generates the filtered results based on the various filtering strategies based on the one or more sequencing quality indicators.
