Schematic workflow of the Functional Genomic Imaging (FGI) analysis. A The TPM/FPKM data matrix was filtered and processed using WGCNA, producing a gene distance matrix. Phenograph was applied to identify coexpression gene clusters, which were then visualized using t-SNE. Based on this, functional annotation, gene expression profiling, and cancer subtyping were performed to gain more detailed insights into gene expression patterns within different cancer types and their clinical relevance
