OpenTEA 2 installation instructions

This is a guide for installation. For more, see the documentation online.

Before you start

There are a couple of dependancies with OpenTEA 2.X, namely:

  • wish v8.5+ (except for the starpack).
  • python 2.6+ but not 3.X
  • numpy v1.10 or higher
  • scipy v0.15 or higher
  • h5py v2.6 or higher

OpenTEA is tasked with executing locally and on distant servers many shell commands. This process is guaranteed only for the bash shell in OpenTEA to date.

The installation is described for an installation with everything in your home directory ~/. Please adapt according to your needs and permissions.

.bashrc file setup

Copy the following in your .bashrc. Don’t forget to source this file again when you are done.

export OPENTEA_HOME="~/opentea"
function opentea {
    wish $OPENTEA_HOME/tcl/opentea.tcl -custom ~/opentea_custom.ini $* &

Configuration file setup

There are two configuration files for opentea: an xml file and an ini file. A default ini file is provided in the repository. For the xml, you have to create it and paste the following in it:

Content of the opentea_config.xml:

<?xml version="1.0" encoding="utf-8"?><dataset>

          <config value="">
                <accounts value="">
                      <tool_plugins value="local_mac">
                            <local_mac value="">
                                  <nbprocs value="1"/>

For this installation in your home directory do:

cp $OPENTEA_HOME/opentea_custom.ini ~/
cp $OPENTEA_HOME/opentea_config.xml ~/

The opentea command line only reads the opentea_custom.ini file, which is a user editable configuration file for your OpenTEA installation. The default “opentea_custom.ini” file is thereafter displayed. This file can be changed by the user to adapt to its installation.

Note that the opentea_custom.ini file contains a link to the opentea_config.xml file. It must be edited by starting the config app from inside any opentea app. Config Config2

  • localEnvironmentVariables: adding or replacing your environment variables in the OpenTEA processus. See environment variables.
  • openteaConfiguration: the core configuration elements.
  • openteaCustomAppearance: to set the background image of the main menu and the icon at the bottomleft of applications.
  • externalApps: add new apps to opentea. The path to the application (containing both XML and scripts folder) is required. See adding New apps.
  • customAppClusters: set up the clusters of apps diplayed in the main menu and in the topbar “Applications” menu. An app must be at least in one cluster to be reachable.

Environment variables

OpenTEA cannot affect your terminal environment. Do set the environment variables that can influence OpenTEA in a single, well identified file. Use $FOOBAR in .ini file or self.env[“FOOBAR”] in python plugins to rely on environment variables

If you declare these environment variables in the .ini file (localEnvironementVariables), only OpenTEA processes (GUI) and subprocesses (when hitting Process buttons) will use these variable. By doing so, OpenTEA cannot be affected by your terminal enironement.

You also can use the general declared variables (e.g. what you have in your .bashrc) . By doing so, your terminal environment is given to OpenTEA at its startup. If you change the environment of your terminal, OpenTEA will not propagate the changes.

Last information: The PYTHONPATH environment variable used by OpenTEA is reset at startup to avoid history hazards.

Using Git to switch between versions

If you are using git to organize your OpenTEA workplace, the recomended arobsence for your instalation is the following

       opentea/         # git repository
       avbp/            # git repository
       avsp/            # git repository
       plugins/         # set your custom XML and .py plugins here
       opentea_custom.ini # your .ini file
       opentea_custom.xml # your .xml file

Keeping several versions, without Git

If you do not use git, and need a tracability of your versions, the recommended arboressence for your installation is the following

       opentea/opentea2.1.0-rc.6/  # the archives, keeping the tag name
       avbp/avbp7.0.1-SEPT2017-rc/ # the archives, keeping the tag name
       plugins/         # set your custom XML and .py plugins here
       opentea_custom.ini # your .ini file
       opentea_custom.xml # your .xml file

In both cases, the GITLAB/plugins/ folder is a copy of the template folder /plugins/ shipped with the opentea archive. Feel free to remove our .xml templates, but keep the no_plugin.xml in both tool_plugins and code_plugins

Checking your installation

To check everything went well, fire up the “playstation” menu:


You should be able to open the app of your choice from the list. Once the app is launched, reach for the Config menu to start the config app. There you can edit and personnalize your config file (saved as config.xml). Please setup your plugin according to your platform. This determines where the setup tools will be run (not the codes, only the setup / post-processing tools).

You can try out some of the example applications:

example: A simple one tab calculator

example_lite: A multitab exemple with inputs and outputs

example_complex: A complex application that uses various options and display 3D

At startup, please read carefully the console output, which should be like:

Local environment variables: 
    |OPENTEA_HOME : /Users/dauptain/GITLAB/opentea
    |AVBP_HOME : /Users/dauptain/GITLAB/avbp
    |AVSP_HOME : /Users/dauptain/GITLAB/avsp
Opentea configuration: 
    |focusCorrection : 0
    |autoSave : 1
    |guiWidth : 1200
    |guiHeight : 680

(-_- ;) application -simplecad- not found
(-_- ;) application -yales2- not found
(-_- ;) application -flametransfer- not found

This output will show how OpenTEA is responding to your configuration. For example, the startup log explain which and why some application were not loaded. If minor errors are presents, there will be warning statement (-_- ;) (breaking a sweat). In case of major error, the is an exit statement t(-,-t) (fck ff).

Adding new apps

When a code has a built-in OpenTEA interface, the engine needs to know how to find it on startup. This is done using the `custom.ini file:


Note that the my_app folder should contain at least the two following folders:

  • XML/
  • scripts/

In case of complex apps that can be called by other apps, an file can also be present in this directory.

Faster startup

The OpenTEA command line call accepts some additional arguments:

  • -code my_app: start my_app directly
  • -file project.xml: load a project on startup

You are welcome to define new aliases for the commands you use often.


Please direct all feedback to the CERFACS team in charge of OpenTEA.
