 Note that in cfg.foi we are now specifying a list of frequencies with steps of 1 Hz. It is also possible to specify a range (cfg.foilim = [1 30];) which will output an average power over these frequencies,​ or to take different size “steps” (cfg.foi = [1:2:30];). Note that in cfg.foi we are now specifying a list of frequencies with steps of 1 Hz.

-We might go further into the output of ft_freqanalysis in a future release of this document but for now it suffices to say it gives a datastructure as output similar as the input structure but now with the field ''​.powspctrm''​ instead of ''​.trial''​ or ''​.avg.trial''​. +We might go further into the output of ft_freqanalysis in a future release of this document but for now it suffices to say it gives a datastructure as output similar as the input structure but now with the field ''​.powspctrm''​ instead of ''​.trial''​ or ''​.avg.trial''​.
