<P class=MsoNormal><FONT face=Arial color=navy size=2><SPAN

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>

style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">as output you can get
TFR for one subject in one condition (but it 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>
