Evoked.get_peak() can search for peaks in the following ways:
-
take the absolute value of the data (i.e., turn everything into non-negative values), and find the largest value of that (that’s the default,
mode='abs') -
only consider positive values (i.e.,
>0), and find the highest value (mode='pos') -
only consider negative values (i.e.,
<0), and find the smallest value (mode='neg')
There is currently no way to use get_peak() to find the smallest value of a signal that’s always positive; or the largest value of a signal that’s exclusively negative.
