Installing and running

To run this experiment in PsychoPy generator:

1. Clone the git repo:

   git clone git@github.com:pyflies/EriksenFlanker.git 
   # or without github account
   git clone https://github.com/pyflies/EriksenFlanker.git
   

2. Go into the folder and crate Python virtual environment:

   cd EriksenFlanker
   python -m venv venv
   

3. Activate Python virtual environment:

   source venv/bin/activate
   

4. Install PsychoPy generator for pyFlies:

   pip install pyflies-psychopy
   

5. Generate Python code:

   textx generate eriksen.pf --target psychopy --overwrite
   

6. Run it under PsychoPy:

   • Install PsychoPy
   • Run

     python eriksen.py
     

Notes

• If you change the pyFlies model eriksen.pf you can regenerate the code with step 5 and then rerun with python eriksen.py.
• You have to source the Python environment (step 3) for each new terminal session.
