Hello, Melina.
Thank you for your interest in the UCSC Genome Browser and for sending your inquiry.
Unfortunately, we do not maintain the CRISPR track hubs by the Giraldez group. The CRISPR track hubs are hosted remotely, meaning that the data is not on our own servers. We would recommend reaching out to the Giraldez Lab (
https://www.giraldezlab.org/people/) and asking them to make their hub accessible again.
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.
