Amplitudes values multiplied by unknown constant (Y axis skewed)

Hi Shady,

I have two guesses:

  1. The time series in Brainstorm have amplitudes in [fT] for MEG, and [μV] for EEG. However, when exported the units are [T] and [V]. This will lead to scaling factor of 1×10^-15 or 1×10^-6 for MEG and EEG signals respectively.
  2. Other potential source of the difference could be that the visualization Filter in Brainstorm is active. Thus the data will look smoother in Brainstorm than in the CSV data.

If none of these two options explain the difference. Can you upload more information?
For example, a screenshot of your data in Brainstorm and the CSV file that was created.

Best,
Raymundo
