So if you look at https://bioconductor.riken.jp/packages/3.2/bioc/vignettes/ChIPseeker/inst/doc/ChIPseeker.html you will notice that most of the data generated is centered on the TSS.
I would like to know if it is possible to center metagene plots (and other data) either at the start of exons / introns / or exon/intron junctions or in the middle of exons themselves?
I am aware that exons all vary in length so that any firm known middle of the exon does not exist, but perhaps there is a way to normalize exon length throughout the hg19 genome?
Is there anything similar to the TSS but for exons? Introns? Junctions?
