Dear all,
We have our own galaxy instance and the idea is to have trackster enabled for users to be able to visualize NGS mapping. We were able to configure trackster in our instance and the visualization works fine.
We have two questions regarding trackster: 1) We can't display genomic sequences in trackster. As per the tutorial, we set the location of the .2bit file in the twobit.loc file for the trackster to be able to display the genomic sequence but for some reason it doesn't display it. The name of the builds is the same in all places i.e) in ucsc/chrom/builds.txt and also in the .loc files. Any ideas on what else should be done?
2) While saving the visualization, there is always an error message saying "could not save visualization" and it doesn't seem to be a web browser issue. How do we then save the visualization?
Thanks in advance, Naharajan
Hi Naharajan,
My best guess is that you've found some bugs. Fortunately, they are likely fixed in galaxy-central and will soon be available in galaxy-dist (we're planning an update in the next couple days). Once galaxy-dist is updated, please try updating your Galaxy instance and seeing if that fixes the problems.
If not, let us know and we can take a closer look.

Hi Jeremy,
So, we updated our galaxy instance and now the genomic sequences can be displayed, when sufficiently zoomed in and also the visualization can be saved now. It looks really nice :-)
Thanks a lot for your help.
Regards, Naharajan

Hello! I am trying to enable Trackster on our local galaxy to visualize the mapping results. But, so far, it is not working. Is the twobit.loc file necessary for using Trackster? or is it just optional?
Best regards, Menorca

Twobit files, configured via twobit.loc, are optional. Here is a page that lists all the steps required to get Galaxy genome visualizations (including Trackster) working: http://wiki.galaxyproject.org/Visualization%20Setup
Let us know if you run into any problems or have questions.
Thanks, J.
