The variable `expyriment.control.defaults.open_gl` can have the following values:

```
0/False = no OpenGL (no vsync / no blocking)
1 = OpenGL (vsync / no bl…

Make first sure that setuptools and wheel are up to date:

```
pip install -U setuptools
pip install -U wheel
```

Then from within the `expyriment-ma…

No. OpenGL is crucial for that. And even then I would suggest to check with the test suite.

That is because `fast_stimuli == "cruel"` and `fast_stimuli == "love"` can never be true, since `fast_stimuli` is a list, and "cruel" and "love" are strings.

Here is a description of the plugin system in Expyriment: http://docs.expyriment.org/Plugins.html.

You can use the MIDI input like this:
```
import expyriment.io.extras

Hi Friedrich,

there is no particular code for recording musical performances, but there is MIDI input and output available as a plugin (see http://stash.expyriment.org). I am not sure …

I moved it to the OpenSesame section (assuming this is where it belongs).

Hi there,

what exactly do you want to do? Since you mention MEG, it seems that you would like to send markers to the MEG system?

If so, you can use the `io.MarkerOutput`…

So from what I can see is that you are adding all 6 stimuli to the same canvas. From your description above this is not what you want...
Simply creating a canvas stimulus in each trial, would …

Not sure if I understand you correctly, but wouldn't this work:

```
def create_random_stim():
sequence = ["R"] * 27 + ["B"]
expyriment.design.randomize.shu…

What I meant is, you put in the data manually into the data file object (usually by doing something like `exp.data.add(my_data)`. So, since you already have the data, before you manually put it into …

Prepare the following stimuli before stimulus presentation:
- `mask = expyriment.stimuli.Picture("...")`
- `prime = expyriment.stimuli.Picture("...")`
- `target = expyriment.stim…

It is not clear to me what your goal is. I understand that your code apparently does not do what you want it to do, but I don't understand what it is you want it to do.

You first menti…

Given the refresh rate of 60Hz, here is what your script does in case SOA is 50:

- it presents the screen_mask stimulus for 3 frames (50 ms)
- it presents the prime_screen s…

Thanked by 1ariannaf
Dear Arianna,

What is your screen refresh rate? I am asking, because you use timings (49ms) that do not seem to fall at multiples of common refresh rates (e.g. 60Hz, 100Hz, 120Hz).

Mmh, I am still a bit puzzled about why this happens. We will look closer into it.

Thanks for the suggestion of a tutorial for more advanced users. This is certainly a good idea.

Howdy, Stranger!
