I have been using deeptools plotHeatmap to generate heatmap around TSS regions from my chip-seq data.
However there are black lines in my heatmap and I don`t know what those lines stand for.
Here is my code:
plotHeatmap -m [prefix]matrix.gz -o [prefix]normalized.png --boxAroundHeatmaps no --colorMap bwr --heatmapHeight 15 --heatmapWidth 3 --whatToShow 'heatmap and colorbar' &
And here is what I got:
Any ideas are appreciated
