External Email - Use Caution

Hello,

I am trying to compute the PSD of Epochs data at source level using multitapper (compute_source_psd_epochs function). This is very time consuming and I am only interested in the average PSD over epochs; however I didn't find anything to calculate the PSD at source level on an Evoked object.

Thanks in advance,

Fleur

hi Fleur,

I would recommend you to follow this tutorial.

https://mne.tools/stable/auto_examples/inverse/plot_evoked_ers_source_power.html?highlight=dspm%20power

It's not based on multitaper but maybe it's good enough?

Alex
