Hi all, I'm trying to get confident coordinates for the Y human centromere (NCBI36) and have found that there are two pairs of coordinates whereas for the rest chromosomes only one pair is present. Could anyone clarify me this please. I'm sorry if this just reflects some ignorance about the Y chr particularities. I followed these instructions and come up with the next table.
