Dareplane CopyDraw module

This repo contains the python implementation of the copy draw recording and analysis pipeline

Config

Configuration files are stored under ./configs

Testing

You should be able to test a single run with This

python -m copydraw.main 

--> If this is not working, something is still odd in the setup

Calibration

Some calibration of scaling an shifting of the trace might be necessary, depending on the aspect ratio which is being used for the copydraw psychopy window. This is due to the trace being displayed as a png background image instead of rendering it as a psychopy trace. We had to resort to this in order to keep up a higher frame rate of recording (usually > 80hz) It is best to check the calibration by running this:

python -m copydraw.main --for_calibration=True

Should the traces and control points be non overlapping, you have three places to adjust:

1. in copydraw/elements.py

    'template': {
        'units': 'norm',
        'pos': (-0.0, 0.01),
        'interpolate': True,
    }

The 'pos' parameter can be used for translations.

2. in copydraw/copydraw.py

    def create_frame(self, stimuli_idx, scale=True, for_calibration: bool = False):

        self.frame['elements'] = {}
        self.frame['elements']['template'] = create_element(
            'template',
            win=self.win,
            image=template_to_image(
                self.get_stimuli(stimuli_idx, scale=scale),
                f'{self.stimuli["fname"][:-4]}_{stimuli_idx}',
                self.paths['data'].joinpath('template_images'),
                linewidth=15,
                for_calibration=for_calibration,
            ),
            size=self.block_settings['size'] * 1.67,
        )

Here the size parameter is used for an isometric scaling of the picture.

3. in copydraw/utils/template_tools.py

def template_to_image(template, fname, path, for_calibration: bool = False,
                      scale: float = 1, **kwargs):

    # if template images dir doesn't exists make it
    path = Path(path)
    path.mkdir(exist_ok=True, parents=True)

    fullpath = path.joinpath(f'{fname}.png')

    if not fullpath.exists():
        # fig = plt.figure(figsize=(16, 10))
        fig = plt.figure(figsize=(16, 9), frameon=False)

Here you can adjust the figsize according to the target screen.

Server

Like for other Dareplane modules, one can manually spawn the server via

python -m api.server

and after connecting e.g. via telnet 127.0.0.1 8080, try sending a START_BLOCK to run a single block of copydraw.

Installation Windows

Use anaconda, normal python interpreter under windows will require tons of extra set up due to some libraries not being properly compiled for windows.

1. conda create --name copydraw python=3.9
2. conda activate copydraw
3. conda install -c conda-forge pywinhook
4. install the rest of the dependancies using pip install -r requirements.txt from the root of this repository
   • it's possible there are dependancy conflicts because of different versions, just loosen them up by replacing library=2.0 to library>=1.5 so that the version conflict is resolved.
5. Download this, install the driver from the win32 folder and copy inpoutx64.dll from the x64 folder to C:\Windows\System32

problems with Pyo?

• Python 3.10 - download this python whell and use pip install pyo_version.whl to install pyo.
