<p class=MsoPlainText><font size=2 face="Courier New"><span lang=EN-GB
style='font-size:10.0pt'>Depending on what you would like to do with your data
- possibly plotting and statistical evaluation -, you may find the example
script on the Fieldtrip homepage very useful: <a

<p class=MsoPlainText><font size=2 face="Courier New"><span lang=EN-GB
style='font-size:10.0pt'>besa2fieldtrip converts the tfc files to a structure
similar to the output of ft_freqanalysis so freqanalysis itself is not needed.
The script shows you how to perform a grand average and how to carry out a
statistical test. (It compares the output of the function clusterrandanalysis
with the new function freqstatistics - you only need the latter.)<o:p></o:p></span></font></p>
<p class=MsoPlainText><font size=2 face="Courier New"><span lang=EN-GB
style='font-size:10.0pt'>As explained in <a
href="http://fieldtrip.fcdonders.nl/tutorial/cluster_permutation_freq"
title="blocked::http://fieldtrip.fcdonders.nl/tutorial/cluster_permutation_freq">http://fieldtrip.fcdonders.nl/tutorial/cluster_permutation_freq</a>,
which may also be of interest to you, Fieldtrip offers several methods for
addressing the multiple-comparisons problem. In the script, the method
cfg.correctm = 'cluster' is selected. For this, you will currently need some
functions from the Image Processing Toolbox although I understand that in the
long run, Fieldtrip will include some free functions for the benefit of those
who do not have this toolbox. <o:p></o:p></span></font></p>
<p class=MsoPlainText><font size=2 face="Courier New"><span lang=EN-GB
style='font-size:10.0pt'>Also, for some options the Statistics toolbox may be
required.<o:p></o:p></span></font></p>

working with a BESA version prior to the BESA Research 5.3 that has just been
released? The new version 5.3 features a comfortable direct MATLAB interface so
you can transfer directly from BESA Research to a MATLAB structure - e.g.
automatically by batch commands - and bypass export to and reading from tfc
files. <o:p></o:p></span></font></p>
