No signal with review raw file

Hello,

When we import data with “review raw file” all the signals are flat but when we import MEG/EEG, there is a signal.

Moreover, when we standardize the “review raw file”, we can see a “good” signal.

We don’t know if the raw file signal is valuable or not.

Thank you for your answer.

Hi @lakamionette,

This seems to be a case of visualization.
When displaying the raw signals make sure that you are removing the DC component (select DC button in the Toolbar of the Record tab)

Thank you
