This feature provides expression matrix plots based on a given gene list. The density of color in each block represents the median expression value of a gene in a given tissue, normalized by the maximum median expression value across all blocks. Different genes in same tumors or normal tissues can be compared in one plot.

Parameters

• Gene List: Input a gene list of interest. Manual input of genes split by comma (e.g. ERBB2,EGFR) is also acceptable.
• Dataset/Tissue Order: Select cancer types of interest in the “Dataset” field and click “add” or “all” to build a dataset list in the “Tissue Order” field. Also, manual input of cancer types split by comma (e.g. ACC,BRCA,BLCA) is also acceptable.
• Log Scale: Choose whether to use linear or log₂(TPM + 1) transformed expression data for plotting.
• Matched Normal data: Select “Only TCGA tumor”, “TCGA tumor + TCGA normal + GTEx normal” or “TCGA tumor + TCGA normal” for plotting.
