- MNE version: 1.7.1
- operating system: Windows 11

What is the reason why there are no psd\_welch and psd\_multitaper in the MNE1.7.1 version I downloaded, is there a new function to replace them or something else? (I tried reinstalling and updating mne to no avail). I cannot import name ‘psd\_multitaper’ from ‘mne.time\_frequency’.

Hello, to compute the PSD on an MNE object, call its `compute_psd()` method, for example `epochs.compute_psd()`.

Best wishes,
