Embodiment
[0068] In this example, human chromosome 22 with an effective reference sequence size of 35Mb and an actual size of 51Mb is used as the analysis object, and the original data processing method of the third-generation nucleic acid sequencing of the application is used for error correction. details as follows:
[0069] 1 Data processing
[0070] 1) The second-generation data and the third-generation data of human samples were respectively obtained through NCBI for testing.
[0071] 2) Using blasr, a global comparison software for single-molecule real-time sequencing long sequences, compared the third-generation data to the human genome hg19, extracted the third-generation sequencing long sequences on chromosome 22, and obtained a data volume of 3.14Gb, N50 It is 11.46Kb. That is, the third-generation long sequence data of step (b) in the processing method of the present application.
[0072] It should be noted that the third-generation data in this example are directly compar...
