I am trying to create a heatmap of differentially expressed lncRNAs in normal, atypical, dcis, and invasive breast cancer patient samples. I have created a heatmap from the counts file but that seems to be the cumulative count of the 4 conditions for each lncRNA and the lncRNAs with the highest total count are represented first or ranked first. I would like to see how the expression (gene count) changes between the 4 conditions for each lncRNAs to see how they are going up or down in expression from normal breast tissue to breast cancer. Is there a way to achieve that? If someone is able to help with this, I would truly appreciate it.
