Hi all, I'm interested in locating some genomic positions to genomic locations in terms of intron, exon, UTR end so on. I've read that the locateVariants function can do this; however, for each genomic position there are several rows corresponding to all positions in the different isoforms. How can I locate my genomic positions (in terms of exon, promoter, UTR and so on) only for canonical transcripts, or how can I identify the genomic location corresponding to canonical isoforms? Thank you in advance for your time and help.
