Hi everyone. I am trying to annotate CpG sites from my downstream analysis. But when using annotateWithGeneParts(), sometimes it returns more than one feature (exon, intron, promoter...) for a single methylation site. What is the purpose of this? I think a single nucleotide can only overlap in one region. When I try to draw a pie chart to visualise the proportions of the features, it allows me to prioritise the regions to get 100% in total. Otherwise it draws bar chart. Thanks in advance.
