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

[Schoffelen, J.M. (Jan Mathijs)]

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) with

ft_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.



Thanks in advance for your help,

Francis
