Embodiment 1
[0122] Example 1 Construction of risk assessment model for intestinal polyps
[0123] 1. Data source and acquisition
[0124] All the data for constructing the intestinal polyp risk assessment model were downloaded from the TCGA and NCBI-SRA databases. The expression files of colorectal cancer and adjacent cancer were downloaded from the TCGA database, and the raw data of intestinal polyps were downloaded from the NCBI-SRA database. A total of 443 samples of colorectal cancer cases, 31 samples of intestinal polyps, and 72 normal samples were selected from the retrieval, and a total of 546 sample data were used for further screening and quality control.
[0125] 2. Raw data processing
[0126] Use fastp software for joint processing and quality control to obtain cleandata. The steps include:
[0127] a. Joint treatment
[0128] Use the double-end sequence automatic detection mode of fastp software to process the adapter;
[0129] b. Data pruning and quality control
