This is a web app that allows you to analyze EEG steady state data recorded by a Brain Products Xon device. It does not process any event markers, it will just run a FFT on the full data set. There are some inputs you can specify, but we recommend you use the default values.
Note. The viewer assumes a CSV file with 8 channels of EEG data from a Xon. Nothing else. So your file must be 8 rows x n samples or n samples x 8 columns. If you do have a marker channel, the app viewer will remove the first channel if you select to do so. Also, you can optionally remove the BIP channel from analysis (recommended if it has no data on it).
