Hi!
I want to ask you how can I extract (and export) data from my ERP in Brainstorm, data like amplitude, latency and mean area.

Thanks in advance!

(I already tried but has not success, in the display the ERP peak at 100 ms is -4 µV, Then I go to Run --> Extract --> Values (or something like that), I wrote 100 ms in both input box for time segment, let other options unselected (except concatenate time 2), then I got the next number:

-3.9803e-6

???

From the interface, if you select a time window, it should show the min/max value at the bottom of the figure.

If you want to extract more formally the values and save them in a file, you can use the process “Find maximum in time”. The values are saved in Volts. If you have values in microvolts, it means values in the range of 10^-6.
-3.96e-6 V = 3.96 uV

I see!

I thank you for answering my questions, I really do.
