For more information have a look at the Matrix website.

The people who created Matrix also run the flagship implementationd of software to connect to the Matrix network, named Element (but there are many alternative implementations). Note that the Element website also provides professional/commercial hosting for Matrix servers (the equivalent to running your own email server), but this i

Sorry I misunderstood before.

What you want to achieve is possible in two ways.

1. Within Expyriment, by manually defining how to process control keys (e.g. ESC) in all wait functions you use:

def custom_process_control_keys():
    expyriment.io.Keyboard.process_control_keys(quit_confirmed_function=convert_variables)

# Simulated data (20 'rest' volumes followed by 20 'task' volumes)
Y = np.hstack((np.random.normal(4200, 50, size=20),
