<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>First, yes, you have to do freqanalysis on
the preprocessed data of the individual subjects for all conditions that you
want to compare (i.e. the input for this function contains all trials from one
subject in one condition.) And it is also important that the other input for
this function is the cfg where for example, in the cfg.method you have to
specify what kind of time-frequency analysis you want to use. (You have to
write ‘wltconvol’ for wavelet transformation and ‘mltconvol’
for multitaper analysis.)<o:p></o:p></span></font></p>

is also possible to keep the information for the individual trials of the
condition by specifying cfg.keeptrials = ‘yes’). When you have the
TFRs for each subject you can grandaverage them with freqgrandaverage where the
input is the TFRs of all subjects (and before averaging you can use also
freqbaseline for giving a baseline for your TFRs).<o:p></o:p></span></font></p>
