So the splice site starts/ends are located here: https://storage.googleapis.com/alphagenome/reference/gencode/mm10/gencode.vM23.splice_sites_starts.feather and https://storage.googleapis.com/alphagenome/reference/gencode/mm10/gencode.vM23.splice_sites_ends.feather.
We have not processed mouse polyA sites, so don’t have a feather file for that.
