How to install o_ptb

Requirements

In order to develop and run experiments with o_ptb, you need to have:

1. Matlab 2019b or higher

2. The signal processing toolbox of Matlab

3. A current version of the Psychtoolbox

If you want to use a Labjack device to trigger, you also need a recent version of python.

Download o_ptb

The preferred way to download o_ptb is via git. This enables you to easily update o_ptb to the most current version. You can also download it directly from the gitlab repository as a zip file, but this method is not recommended.

Assuming, you have git installed on your computer, you can download o_ptb by “cloning” the repository.

Open a terminal and navigate to the folder under which you want to find o_ptb.

Let’s suppose, I have a folder called matlab_toolboxes where I store all my toolboxes for Matlab:

cd matlab_toolboxes
git clone https://gitlab.com/thht/o_ptb.git

This should be rather quick to finish. You should now see a new folder called o_ptb.

Keep o_ptb up-to-date

o_ptb is under constant development. Make sure that you always keep your version updated. In order to do so, open a terminal, navigate to the folder in which o_ptb lives and issue pull command of git:

cd matlab_toolboxes/o_ptb
git pull

Where to go next

Now that you have successfully installed o_ptb, you might want to take a look at the tutorials.
