I'am trying to open index.html from JBrowse after running ./setup.sh.
I have just loaded sample_data of volvox.
But some of the tracks are not loading file.
Showing "Error : HTTP 200 when fetching file"

Please help me in this
Thank You.!

The setup data should work, however, it looks like you are trying to run it on your local client machine using the file:/// protocol in the browser? 

If that is true, try using the JBrowse-1.16.1-desktop-linux-x64.zip from the following site, it is likely more appropriate to your needs.

I use JBrowse on a server only, but the local version is attractive for some colleagues.
