[Eeglablist] Time-frequency analysis

[Francesco Lomi]

Hi everybody,

I would like to analyze my dataset computing the ersp and itc
matrices. When I plot the single-channel time-frequency plots for each
subject they seem ok, but when i precompute the ersp from group
analysis (using the default parameters: 'cycles', [3 0.8], 'nfreqs',
100, 'ntimesout', 200) the plot results are strange and do not
resemble the one of single-subject data. Is this probably related to
the default parameters that are not suitable for my data? I have a
1000 sampling rate, -600 +600 epoch length (1201 data points) and I
would like to plot the frequencies between 8 and 45 Hz. How should I
modify the ersp parameters?
Thank you so much,
Francesco
