Detailed Documentation
In this article, we present MATLAB source code and data files for GEO expression profile analysis. We begin with an overview of GEO expression profiles, including their background significance, data acquisition methods, and contributions to gene expression research. We then provide detailed explanations of MATLAB analysis procedures, describing the functionality and applications of each program. The implementation includes key functions for data preprocessing, normalization algorithms, and statistical analysis methods commonly used in transcriptomic studies. Finally, we offer sample data files with corresponding code examples, enabling readers to practice using these programs and conduct their own data analysis workflows. The code demonstrates practical approaches for handling microarray data formats, performing quality control checks, and implementing differential expression analysis pipelines.
