I will like your advice in how to present the DE genes in a heatmap. I will like to show around 40 genes of interest, their log2FC varies between -1.3 to 5.4, but most of them range between -1 to 1. One gene can be DE (FDR<0.05) in one but not all the datasets and I want to show this in the heatmap. But not sure how to deal with them, if a put NA then the heatmap will have empty scales, is it appropriate?
My other question is if I convert my log2FC to FC [2^dataE$log2FC], I will get greater numbers and make the heat map colours more contrasting. But I am not sure if the adjusted pval will still support FC values.
Hope is not very confusing.
