Windows XP / Vista / 7
There are a number of ways to run OpenSesame under Windows:
- Use the automated installer (see link above). After installation, you can run OpenSesame from the start menu.
- Download the Windows portable .zip file (see link above) and extract it to a location of your choice.
- Download the package based on Python portable, which comes with a slightly different set of modules. For more information, see this article.
Ubuntu/ Debian/ Linux Mint
The recommended way to install OpenSesame under Ubuntu/ Debian/ Linux Mint is through the NeuroDebian repository (see their instructions on how to add NeuroDebian to your list of repositories). After you have added NeuroDebian to your software sources, you can install it using your package manager (Synaptic/ Add remove programs/ Ubuntu software center) or by typing the following lines in a terminal:
sudo apt-get update
sudo apt-get install opensesame
If you encounter problems or if your distribution is not supported by NeuroDebian, you can also install OpenSesame via the ppa:smathot/cogscinl Ubuntu repository. If you experience missing icons, please install the package gnome-icon-theme-full.
sudo add-apt-repository ppa:smathot/cogscinl
sudo apt-get update
sudo apt-get install opensesame
After you have installed OpenSesame, you can start OpenSesame from the menu or by opening a terminal and running:
opensesame
Mac OS
Support for Mac OS is experimental. Instructions for running OpenSesame from source on Mac OS can be found here. The latest versions of OpenSesame (> 0.27.1) come in two flavors. One runs on 64-bit Python (from python.org) and of all its underlying packages were obtained by using the official distributables that are available from the developers’ websites. Because psychopy is not able to run in a 64-bit Python environment (yet), this backend is not available in this version. The other version is completely built from the ground up with macports and is compiled in 32-bit. This version does contain the psychopy backend. Concerning their usage, there are no real noticable differences between these versions (except for the lack of the psychopy backend in one) and experiments created in one version should work perfectly in the other, so the decision of which one to use is completely up to you (upon initial testing, the 64-bit version seemed a bit more stable, but these tests were not really in-depth)
Both versions have been built on Mountain Lion and, after initial tests on our systems, sadly did not seem to be backward compatible with older OS X versions. If they do work for you on pre-Mountain Lion macs, please let us know on the forum.
An older version of OpenSesame which should run on all OS X versions (>10.6) can be found here:
We are looking for someone to improve and maintain the Mac OS packages for OpenSesame!
Other platforms
If there are no packages provided for your platform, you will need to run OpenSesame from source, as per these instructions.
