A BonVision primitive that creates a sequence of grating parameters used for stimulus presentation.


GratingSpecification allows the creation of an arbitrarily large collection of grating stimuli with different parameters that can be specified from their input Trials.


  • Needs DrawStimulus (the tag for rendering a frame) as an input to be able to run
  • Trials: opens a window in which set the parameters of a collection of grating stimuli (trials)


  • This node is to be connected to EnsureGratingParameters
  • All the properties that are externalised can be sent forward as outputs.
