Dear Jason,
Thank you for your question about the UCSC Genome Browser. We have hg19 to chlSab1 LiftOver files here. The chlSab1 sequence is 'identical' to chlSab2
however, the chromosome names differ by the presences of v1 on the chlSab2 names. You may also find the rheMac3 to hg19 here and calJac3 to hg19 here.
I hope this is helpful. If you have any further questions, please reply to gen...@soe.ucsc.edu. All messages sent to that address are archived on a publicly-accessible Google Groups forum. If your question includes sensitive data, you may send it instead to genom...@soe.ucsc.edu.
