Data analysis method and data analysis device for MLPA-NGS kit sequencing data

The invention relates to a data analysis method and a data analysis device for sequencing data of an MLPA-NGS kit. The data analysis method comprises the following steps: acquiring a to-be-analyzed sequencing file; analyzing and processing the sequencing file according to the characteristic sequence file to generate an engineering file; processing the project file according to the characteristic project file to generate drawing data; and drawing according to the drawing data to generate a graph file. The data analysis device comprises a sequencing operation unit, an engineering operation unit and a picture operation unit. The method has the advantages that a fastQ file obtained through MLPA-NGS is automatically analyzed without decompression, and a point column graph, an affiliated chromosome graph, an SNP result graph, a detection quality graph, reads data and the like containing SNP and CNV of each site are generated, so that a user can conveniently analyze a detection result and issue an analysis report; t
