hello

I would like to know the following information:

for raw.load_data().filter(picks=[‘mag’, ‘grad’],l_freq=1,h_freq=50):
filter type, order, cut-off frequencies,direction of filter application (forward, backward, both), and length of filter kernel

for raw.compute_psd(tmin=t_min,tmax=t_max)
Length of time window used, overlap

can you please instruct me how to find this information?

thank you!

Please refer to the following tutorial on our website, which should contain the answers to your filter-related questions:

Regarding PSD computation, the documentation for raw.compute_psd() links to psd_array_welch() for details such as the length of the time window and the default overlap.
