[FieldTrip] Calculating band power or power spectral density with ft_freqanalysis

[fewaster at gmail.com]

Thank you, Jan-Mathijs!

I still have two questions:
1. about average bandpower.
Is your method for calculating average bandpower different from that by integral of PSD?

2. about total band power.
How to calculate total band power instead of average band power in fieldtrip?

Best,
Zhiwei

Hi Zhiwei Fan, 

Averaging across a spectral band these days is done with the ft_selectdata function:

cfg = [];
cfg.frequency = [low high]
cfg.avgoverfreq = ‘yes’;
dataout = ft_freqanalysis(cfg, datain);

Good luck,
Jan-Mathijs

Dear All, I am attempting to calculate band power or power spectral density (then I can use bandpower() in Matlab to calculate band power) withft_freqanalysis but it seems does provide this function. I have found a similar question in  https://mailman.science.ru.nl/pipermail/fieldtrip/2020-February/039790.html However, no one has yet answered this question.I want to know how to calculate band power or power spectral density in Fieldtrip.
