We might think about adding gene exon/intron structures back to the plots in the future, but this is not a priority right now. Right now this is only on the develop branch, so to use it install from the develop branch using devtools: R/visualization. 4. The object will the the Seurat object you're working with, because that contains the data that will be plotted (Tn5 insertion events per position by cluster). In the vignettes, I see that coverage plots are only using data from one batch at a time. What I am looking for is some way to annotate the set of peaks in a given region for their motif enrichment de novo, rather than manually annotating them in the coverage plot. I am making coverage plots from a merged data set of 24 different batches. </p> A list of plots to combine. In your case you need to set the peaks. The ranges.
