On the site when I open the
Spectral Features tab, I see the following error
Error: Digital filter critical frequencies must be 0 < Wn < 1. So I try to make the critical frequency half of the sampling frequency to solve this. I press
Save Parameters button to save the settings.
Then I open the the
Generate features sub tab and press the
Generate Features button, I am greeted with the following error.
