AddRemoveEvoked

Remove or (re-)add average evoked activity to a given continuous signal.

This can be used to alter the signal baseline for artifact removal in the presence of evoked activity. The node should then be used in a manner where first, the evoked activity is removed, then artifact removal is applied, and then the previously subtracted evoked activity is added back in. Note that segmented data must have already been grouped into conditions by setting the TargetValue field of each instance, which can be accomplished using the AssignTargets node. Version 0.5.0

Ports/Properties

data

Continuous data.

  • verbose name: Data
  • default value: None
  • port type: DataPort
  • value type: Packet (can be None)
  • data direction: INOUT

segmented

Segmented data.

  • verbose name: Segmented
  • default value: None
  • port type: DataPort
  • value type: Packet (can be None)
  • data direction: IN

operation

Operation to perform. Remove will subtract the evoked activity captured by the segmented dataset from each trial in the data, while add will add it back in. This can be used to perform certain processing steps in the absence of evoked activity.

  • verbose name: Operation
  • default value: add
  • port type: EnumPort
  • value type: str (can be None)

estimator

Estimator to use for calculating the average evoked activity.

  • verbose name: Estimator
  • default value: mean
  • port type: EnumPort
  • value type: str (can be None)

trim_proportion

Proportion to trim for trim_mean estimator. Applied to both the smallest and largest values in the data.

  • verbose name: Trim Proportion
  • default value: 0.15
  • port type: FloatPort
  • value type: float (can be None)

set_breakpoint

Set a breakpoint on this node. If this is enabled, your debugger (if one is attached) will trigger a breakpoint.

  • verbose name: Set Breakpoint (Debug Only)
  • default value: False
  • port type: BoolPort
  • value type: bool (can be None)

metadata

User-definable meta-data associated with the node. Usually reserved for technical purposes.

  • verbose name: Metadata
  • default value: {}
  • port type: DictPort
  • value type: dict (can be None)
