I am doing DEGs using DESeq2. I am having difficulty drawing a heatmap after DEGs. There is no diffferneces in expression in my heatmap.
After pre-processing the count data, DEGs were processed. 'apply' function was used to create 'mat_scaled' dataframe.
Here is my heatmap. I think there should be differences in gene expression between 'Primary Tumor' and Solid Tissue Normal' in my heatmap.
How should I solve this problem?
