Thank you for reporting the issues you are having with the Table Browser and custom tracks for your hub.
To confirm, are you using the public web site at
http://genome.ucsc.edu and not a mirror or the GBiB virtual browser? Are you still experiencing this issue?
I could not replicate your Table Browser error. I was able to successfully load your hub, where I then went to the Table Browser. From the Table Browser, I was able to export MAF output for all six of your genomes.
As an alternative to a screen shot or html file of your web page, you can send a link to a "saved session." For example, here is a link to my "saved session" where I loaded your hub. You should be able to click on
this
session
link
and get MAF output for your genome assemblies.
You can read more about
creating sessions on the Sessions User Guide. Sessions can
be created from the site-wide menu "My Data > My Sessions."
If you get a chance, it might be helpful for you to send us a saved session where you are getting the Table Browser error.
Second - the custom track issue:For your custom track, you will need to use whatever chrom names you have used in your assembly hub. For Anc0, it appears that you are using the naming convention "Anc0refChr*", so you will need to change your custom track to reflect those names.
Please respond to this list if you have further questions!
