12. You can use karyoploteR to plot your regions on an ideogram quite easily. Disclosure: I'm one of the authors of the tool. For this example I'll start creating 4 GRanges with random regions, but with your data you should load your bed into R and split it into four GRanges. library (karyoploteR) typeA <- createRandomRegions (nregions = 100. We introduce ggbio, a new methodology to visualize and explore genomics annotationsand high-throughput data. The plots provide detailed views of genomic regions,summary views of sequence alignments and splicing patterns, and genome-wide overviewswith karyogram, circular and grand linear layouts. The methods leverage.
