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)
