## OWLViz plugin proposed with Protégé 5.0.0 installed on a Mac El Capitan OSX 11

 Hello, I cannot use OWLViz in Protégé 5.0.0 on my Mac El Capitan (OSX 11). I get this ERROR message : "An error related to DOT has occurred. : This error was probably because OWLViz could not find the DOT application. Please ensure that the path to the DOT application is set properly". This actuel path is /usr/local/bin/dot. I don't know : 1) how to get on that path on my Mac, 2) what that "DOT application" looks like, 3) whether it is installed on my Mac, 4) Wether I should mention another path to get it on Protégé ? Any help ? -- Jean-Louis Janin _______________________________________________ protege-user mailing list [hidden email] https://mailman.stanford.edu/mailman/listinfo/protege-user

 Hi,Have you installed Graphviz [1]? If you already have Graphviz installed you should be able to find the application using a Spotlight search. If not, you need to install it first. After Graphviz is installed, you need to set the “Path to DOT” in the Protege preferences to the correct location of your Graphviz installation.Cheers,RafaelOn Jul 18, 2016, at 10:40, Jean-Louis Janin <[hidden email]> wrote: Hello, I cannot use OWLViz in Protégé 5.0.0 on my Mac El Capitan (OSX 11).

Hello,

Thank you for more help.

I have downloaded graphviz-2.36.0.pkg in the Applications directory of the Macintosh HD and installed Graphviz as an application in the same directory ? What is the "default" location ? Should I install it somewhere else ? What should be the path in the preferences of Protégé ?

Yours

see :

an application in the Essential Viewer requires version 2.26.3 or above of Graphviz.

# Installation Instructions

We strongly recommend installing Graphviz to its default location using the standard installer.

### Default Path

#### Default Path: Windows

c:\Program Files\Graphviz*\dot.exe or c:\Program Files (x86)\Graphviz*\dot.exe

depending on which version of Windows you are using.

#### Default Path: Linux / Mac OSX

/usr/local/bin/dot or/usr/bin/dot

### Environment Variable

If you have installed Graphviz somewhere other than the default location, you will need to define the environment variable GRAPHVIZ_DOT to point to the exact location of the DOT program. The variable must contain an executable, not a directory.

#### On Windows:

Create an environment variable GRAPHVIZ_DOT and point it to the DOT executable.

For example: d:\example\dot.exe

Consult your Windows documentation for help setting environment variables in your version of Windows.

#### On Linux/Mac OS-X

From the command line, use the following commands.

setenv GRAPHVIZ_DOT /usr/local/bin/graphviz/dot export GRAPHVIZ_DOT

You can download these from the following the following location

# Troubleshooting

On OS X Yosemite (10.10.x) Mac, the installation of GraphViz may depend on X11. If you encounter a 'net.sourceforge.plantuml.svek.EmptySvgException' error from PlantUML, please see this forum post for further instructions to resolve this issue.

There’s only one distribution of Graphviz, here’s the direct link to the download page for Mac OS X: http://www.graphviz.org/Download_macos.php. I have installed Graphviz v2.36 on OS X El Capitan, and it is not necessary to install any other (development) tools.

The OWLViz plugin is documented here: http://protegewiki.stanford.edu/wiki/OWLViz.

Cheers,
Rafael
