EnsureGratingParameters

A BonVision primitive that specifies default values for optional parameters in the grating specification.

Description

This node, as the name suggests, ensures the the grating parameters are formatted before

Needs a GratingSpecification node as an input to be able to run
Contrast: contrast of the grating(0 to 1)
Diameter: diameter of the grating in normalised screen units (0 to 1)
Duration: displaying time of the grating (in seconds)
Orientation: orientation of the grating in radians (0 to pi)
SpatialFrequency: cycles per degree
TemporalFrequency: cycles per second
X: x coordinate of the centre of the grating in normalised screen coordinates (-1 to 1)
Y: y coordinate of the centre of the grating in normalised screen coordinates (-1 to 1)
Path: specifies an already save protocol to use for the grating. For example, a collection of grating stimuli with varying orientation or temporal frequency. After choosing the protocol, this node is automatically grouped in a sub-workflow whose name is the name of the protocol.
