octa 1.0.0

A tool for researchers to create stimuli varying in order and complexity on different dimensions

OCTA toolbox

The OCTA Python toolbox was created by Van Geert, Bossens, and Wagemans (2021) as a tool for researchers to create stimuli varying in order and complexity on different dimensions. It was created in Python 3.8 and is dependent on the following Python libraries: svgwrite, svg.path, svgpathtools, svgutils, jsonpickle, html2image, svglib, reportlab, colour, and IPython. We thank the developers of each of these libraries and of the Python programming language.

A simple example:

from octa.Stimulus import Grid
from octa.patterns import GridPattern
from octa.shapes import Ellipse, Rectangle, Triangle

## Create new stimulus
stim = Grid(n_rows = 6, n_cols = 6, background_color = "none",
            row_spacing = 40, col_spacing = 40)

## Determine shape of elements used in the stimulus
stim.shapes = GridPattern.RepeatAcrossColumns([Rectangle, Triangle, Ellipse])

## Determine color of elements used in the stimulus
colors_to_use = ["#1b9fd8", "#6dd6ff", "#006ca1"]
stim.fillcolors = GridPattern.RepeatAcrossColumns(colors_to_use)

## Determine size of elements used in the stimulus
stim.boundingboxes = GridPattern.RepeatAcrossColumns([(30,30)])

stim.Show()

OCTA Shiny app

A graphical user interface for OCTA is available in the form of a Shiny app.
