[Eeglablist] T-F analysis, help with frequency range

[Clemens DICKHUT]

Hi Xianghong,

if you are using the imagesc function to plot, you just need to adjust the axis parameters,
for example


imagesc((analysis.ERP.times), (ERP.freqs), GROUP_ERSP)
axis([-700 700 2 50])
set(gca,'YDir','normal')
title('ERSP Congruent' ,'FontSize',17);

if you use the newtimef function you have to specify the parameters in the function, such as ‘maxfreq':

Hi,

I try to use their time-frequency analysis, by using the plot/time-frequency transforms/channel time-frequency. However, the figure generated only show the frequency range of 15-50 Hz. We want to see the range at least from 1 Hz to 50 Hz, how to rescale the T-F plot?
Thanks,
Best,

Xianghong
