Artifacts Exclusion
Controls what Artifacts are to be excluded from the display set. If an artifact is detected in any epoch on any channel, that epoch is excluded from all channels.
Std Min Dev (Threshold (µV)):
Threshold (µV):
ERPs whose standard deviation of all points within the epoch is greater than the threshold.
Repeated Values (# of Points):
# of Points:
ERPs that have amplitudes within an epoch which are repeated # of times in a row.
Median Outliers:
# of Points:
Find the median amplitude (Am) for all epochs in each channel. Calculate the absolute difference (Dabs) between the amplitude of each point (Ap) and the median amplitude (Am). Average the # largest differences (Dmax). Exclude ERPs which have any point outside the range (Am ± Dmax).
Absolute Max Peak-to-Peak:
Range (µV):
ERPs with a point outside the range of (± the absolute value of the highest amplitude (positive or negative) within the epoch.
Relative Amplitude:
# Multiple:
ERPs with a point with absolute value greater than # times the RMS peak-to-peak amplitude.
Specific Epochs:
Epoch # (e.g. 5, 7-10):
Specifically identified ERP epochs.
NOTE: Artifacts are excluded before any normalization occurs.
Normalization
Controls how the data will be normalized before plotting.
Amplitude:
Peak-to-Peak:
Scales the amplitudes by setting the absolute peak-to-peak range to ± 1.0.
RMS:
Scales the amplitudes by setting the absolute RMS range to ± 1.0.
Drift
Calculates a straight line curve fit for each epoch and rotates the data so that this curve fit becomes the new Y0-axis.
Offset
Calculates the average of the prestimulus interval and offsets the baseline this amount.
NOTE: Artifacts are excluded before any normalization occurs.
