EEG fast-visualization software

Hi everybody,

I’m recording electrical signals to obtain both spikes (high-pass > 300 Hz) and local-field potentials (low-pass < 6kHz) that I collect with 128 channels at 30 kHz (files sizes are ~ 50 Gbytes). I’m using neuroscope for visualization - which is an old-fashioned software of limited capabilities -. I can read the binaries with Python, but the whole process is very slow for a first-and-fast visual inspection.

I was wondering what are the alternatives for EEG visualization and basic editing in the field of EEG recordings. I’ve just discovered physionet.com, and I was wondering what is the standard in the field, and if you guys have some recommendations (preferably under GNU/Linux).

Here an example with only 64 channels.
