MNE version: 1.4.2  
Operating system: Ubuntu 22.04.3

Dear colleagues,

I am sorry for my perhaps not so sophisticated question, I am still learning how to use MNE Python.

I need to compute the MEG signal power after LCMV beamforming. I found different functions for computing power on the MNE website, but they are either applied to raw data or are applied with dSPM, sLORETA, eLORETA, but not LCMV. I have not found a function to compute power after LCMV on the website.

Could you please give me a hint at how I need to tackle this issue?

Thanks so much!
