Genomic-data storage method and electronic device

Abstract

The invention discloses a genomic-data storage method. The genomic-data storage method includes the steps that in the genome comparison process, gene-sequence comparison information is obtained, and gene-sequence statistical information is established; the gene-sequence comparison information is stored in a magnetic disk, and according to comparison positions of the gene-sequence comparison information in a genome, corresponding indexes are stored in a memory, wherein the indexes are storage positions of the gene-sequence comparison information in the magnetic disk; genome statistical information is classified, and first statistical information and second statistical information are obtained; the first statistical information is stored in the memory, wherein the first statistical information is statistical information with the access frequency higher than the preset frequency in the variation detection process; the second statistical information is stored in the magnetic disk, wherein the second statistical information is statistical information which cannot be stored in the memory and / or statistical information with the access frequency lower than the preset frequency in the variation detection process. The invention also discloses an electronic device with the genomic-data storage method.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a genomic data storage method and electronic equipment. Background technique [0002] The calculation process of genomic variation detection can generally be divided into steps such as comparison, sorting, deduplication, re-alignment, variation detection, and filtering. Among them, the main steps need to use the BAM file (the full name of SAM is sequence alignment map, sequence alignment map. And the BAM file is the file in the binary format of the SAM file (B is taken from binary)) as the output file to write to the hard disk, in the next The step is to read it from the hard disk to the memory, and then proceed to the next step. [0003] In the process of realizing the present invention, the inventor finds that the prior art has the following problems: [0004] In the analysis of human whole genome data, the original data is generally about 100GB, and the main analysis...
