Overlapping transcripts between sets of differentially expressed transcripts. A heatmap displaying the number of overlapping transcripts between various differential expression lists. Differential expression is defined here as p-value < 0.01 and fold-change > 2. Both upper left and lower right triangles display the same information, but in different metrics. The upper left triangle (red to blue gradient) shows the percentage overlaps between two differential expression lists. Percentage overlap is calculated as the average of the two overlap percentages generated by dividing number of share transcripts to each of the two differential expression list totals. The lower right triangle (yellow to black) shows the absolute numbers of overlaps between two differential expression lists.
