The structure of gene sequences is also more complex. However, the traditional sequence alignment method is difficult to deal with the complex gene sequence alignment work. In order to improve the efficiency of gene sequence analysis, D2 series method of k-mer statistics is selected to build the model of gene sequence alignment analysis. According to the structure of the foreground sequence, the sequence to be aligned can be cut by different lengths and divided into multiple subsequences. Finally, according to the selected subsequences, the maximum dissimilarity in the alignment results is determined as the statistical result. At the same time, the research also designed an application system for the sequence alignment analysis of the model. The experimental results showed that the statistical power of the sequence alignment analysis model was directly proportional to the sequence coverage and cutting length, and inversely proportional to the K value and module length. At the same time, the model was applied to the system designed in this paper. The maximum storage capacity of the system was 71 GB, the maximum disk capacity was 135 GB, and the running time was less than 2.0s. Therefore, the k-mer statistic sequence alignment model and system proposed in this study have considerable application value in gene alignment analysis.<\/jats:p>","DOI":"10.1371\/journal.pone.0306480","type":"journal-article","created":{"date-parts":[[2024,9,12]],"date-time":"2024-09-12T17:35:51Z","timestamp":1726162551000},"page":"e0306480","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":1,"title":["Gene sequence analysis model construction based on k-mer statistics"],"prefix":"10.1371","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5198-8133","authenticated-orcid":true,"given":"Dongjie","family":"Gao","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2024,9,12]]},"reference":[{"issue":"5","key":"pone.0306480.ref001","doi-asserted-by":"crossref","first-page":"1150","DOI":"10.1016\/j.ijrobp.2020.07.2313","article-title":"Hypofractionated Adjuvant Radiotherapy is Effective for Patients with Lymph Node Positive Breast Cancer: A Population-Based Analysis","volume":"108","author":"T.
