# EEG Grand Averag

## EEG Grand Average BrainVision

The Grand Average transform allows you to generate one or more grand averages based on a

number of different averages. Grand Average is a secondary transform. It stores its results in the

current workspace in the form of secondary history files. Because averages are calculated across

a number of different data sets, it is possible that the data sets included in the calculation may contain

different channels. In the Grand Average dialog box, you can specify how such cases are to be handled.
