Ah, thank you very much, Hans-Rudolf. That did the trick. Best regards, Scott On Wed, Sep 14, 2016 at 6:56 AM, Hans-Rudolf Hotz <hrh@fmi.ch> wrote:

Hi Scott

click on the question mark next to 'database' in your history item and set the "Database/Build" to the genome you need.

Hi all,

I'm getting the following error when attempting to do a trackster visualization:

Error: The requested genome file (/vectorbase/web/Galaxy/galaxy /tool-data/shared/ucsc/chrom/?.len) could not be opened. Exiting! Couldn't open /vectorbase/web/Galaxy/galaxy/ tool-data/shared/ucsc/chrom/?.len

I found a discussion related to this error online at https://biostar.usegalaxy.org/p/6938/, but I'm unsure what the offered solution actually means in terms of what I need to do. It says " You'll need to set your dataset's database/dbkey to your custom reference genome before you can visualize it". Can someone point me in the right direction to solve this issue?

Thanks in advance,

Scott
