This often means that on this UCSC Genome Browser, GraphViz is not installed or is too old and that the supplied program dot_static also did not work. It can also mean that the configuration option graphvizPath in hg.conf specifies a program that does not work.

To resolve any of these problems, you will have to contact the system administrator of this Genome Browser server.

To install GraphViz, ask the administrator of this server to run one of the following commands:
sudo apt-get install graphviz
sudo wget http://www.graphviz.org/graphviz-rhel.repo -o /etc/yum/repos.d/graphviz.rhel.repo; sudo yum install graphviz*

If you have graphviz installed but this error message still appears, then the graphviz version may be too old.

Also, the Genome Browser ships with a statically compiled version of dot, cgi-bin/loader/dot_static. This version should work with a 64bit linux, unless the installed glibc is too different from the one compiled into dot_static.

As a last resort, you can compile GraphViz from source and specify the full path to 'dot' with the option 'graphvizPath' in cgi-bin/hg.conf.
