How can I get the sheep chromosomes centromere position and chromosomes length???

Question

[Emy]

I face to one problem that I can not resolve it. I have a problem for drawing idiogram in sheep chromosomes because I must have sheep centromeres position and chr size in this graph but I can't find information about it. The table below is a sample from human genome.

ID  size            centromere
1   249239465     121535434,124535434
2   243199373     92326171,95326171
3   199411731     90504854,93504854
4   191252270     49660117,52660117
5   180915260     46405641,49405641

Not sure if we have got centromere positions for the sheep genome at all. If we did, I guess we would be able to see that in the Whole genome (i.e. karyotype) view in Ensembl, for example. Even for the rather extensively studied human genome, the centromere representation was big news upon the release of the latest human assembly (GRCh38: Incorporating Modeled Centromere Sequence).

UCSC Goldenpath has a sheep cytoband file used for making ideograms on the UCSC genome viewer, but the file itself does not have the expected annotations that would show cytobands or centromeric positions.

You might contact the authors of sheep genome data here: https://www.animalgenome.org/

They have an ideogram viewer that displays centromere position, so it might be in a data table they publish somewhere or can make available to you.
