Gene sequencing data compression method, decompression method and related device

The embodiment of the invention provides a gene sequencing data compression method, decompression method and related device.The compression method comprises the steps that multiple sets of gene sequencing data are analyzed from an original gene sequencing file, the multiple sets of gene sequencing data comprise one or more of character data, sequence data and quality data, and the character data, the sequence data and the quality data are selected from one or more of the character data, the sequence data and the quality data; the positions of different gene sequencing data in the original gene sequencing file are different; compressing the multiple groups of gene sequencing data based on the type of the gene sequencing data to obtain compressed data; wherein different types of gene sequencing data correspond to different compression algorithms. According to the embodiment of the invention, the problem that the compression ratio of the gene sequencing data is relatively low can be solved, so that the storage c
