Subject: over.chain file request

Hello,

My name is Teemu Lankinen and I represent Blueprint Genetics Oy, Finland. We are a genetic testing company. We’re interested in getting the below chain files. However, it is a bit unclear to us how to access them. Could you please assist us in completing the purchase. We would want just the files and not the LiftOver command line tool.

·         hg19ToHg38.over.chain.gz From: https://hgdownload.cse.ucsc.edu/goldenpath/hg19/liftOver/

·         hg38ToHg19.over.chain.gz From: https://hgdownload.cse.ucsc.edu/goldenpath/hg38/liftOver/

Also, please advise payment method options.

Thank you!

Kind Regards,

Teemu Lankinen

Hello, Teemu.

Thank you for contacting the Genome Browser support team.

Please note that the use of UCSC chain files requires a commercial license. To complete a purchase and discuss payment options, you will need to contact the UCSC Genome Browser Store at genome-browse...@ucsc.edu.

The chain files can be downloaded from the following locations:
https://hgdownload.gi.ucsc.edu/goldenpath/hg19/liftOver/hg19ToHg38.over.chain.gz
https://hgdownload.gi.ucsc.edu/goldenpath/hg38/liftOver/hg38ToHg19.over.chain.gz

I hope this is helpful. If you have any further questions about UCSC Genome Browser tools or data, 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.

Hello,

Thank you for your reply, Geraldo.

(Adding genome-browser-store-group and our Bx Director Mr. Ville Kytölä)

We are looking to use the lift over files as a part of our software. Looking to get the purchasing information as per the first email in this thread. The software may have multiple internal users. How does UCSC define a user in this case?

Also, just learned that our colleague Mr. Christopher Elzinga at Quest Diagnostics, US (Blueprint Genetics is a wholly owned subsidiary of Quest Diagnostics Inc.) has been in contact with Clay Fischer. 

Kind Regards,

Teemu Lankinen
