How to view SEEG channels
Most acquisition systems record SEEG electrodes as EEG electrodes.
There is no way in the data file to distinguish between EEG and SEEG electrodes.
But you can tell AnyWave to consider all or some of the EEG channels as SEEG.
Automatic EEG to SEEG montage
As almost EEG recording systems save data from SEEG electrodes as EEG channels, some operations must be applied in AnyWave to correctly handle those data as SEEG.
This video tutorial shows how to transform EEG channels into SEEG and how to set up a bipolar montage for them.
The video shows how to do it automatically, assuming that ALL the channels recorded are in fact SEEG.
But, sometimes, you may deal with data files containing SEEG recordings AND EEG recordings (and even MEG channels).
In this case, you have to change the channels types manually, in the Montage Interface.
This is easily done by selecting the channels in the left list (As Recorded Channels) and use the context menu to change their types.
After that, you must also ask for a bipolar montage for SEEG channels by clicking on the corresponding button.

How to compute H² on two conditions
If you have data recordings with external stimuli, you may want to compare the correlation between channels before and after the stimulus.
This video shows how to do that:
