Hi, Iām new to MNE. Iām using ātfr_array_morletā to compute time frequency power. I am wondering how to compute the non-phase lock power, should I remove ERP as input data before use ātfr_array_morletā ? And what is the mean of the āzero_meanā parameter, how should I define its value ? Thanks in advance.
Hello @hillhillll and welcome to the forum!
Iām tagging @cbrnr, who might be able to give you some advice here!
Good luck,
Richard
I usually do not remove phase-locked activity when computing time-frequency power. I recommend using mne.time_frequency.tfr_morlet(), which operates on an Epochs objects instead of an array. In particular, this function will return the inter-trial coherence itc in addition, which contains information on phase-locked activity.
Regarding the zero_mean parameter, I am not entirely sure what it means, but Iād go with the default value of True (interestingly, the default is False for mne.time_frequency.tfr_array_morlet(), but I donāt recommend using that anyway).
