<font face="Calibri">Hi everybody,<br>
<br>
We have changed the meaning of phases of <i>raw</i>
Fourier-coefficients of method = 'wavelet' (previously
'wltconvol'), so that it is in alignment with method =
'mtmconvol'. <br>
</font>All output is now phase-shifted such that an angle of 0 of
any Fourier-coefficient always means a peak of an oscillation in the
data, and an angle of pi/-pi will always mean the trough of an
oscillation (wavelet wise angle = 0 is implemented as cosine at
peak, and sine in up-going flank) (also documented in the FAQ
section <a
href="http://fieldtrip.fcdonders.nl/faq/what_are_the_differences_between_the_old_and_the_new_implementation_of_wavelet_formerly_wltconvol_in_ft_freqanalyis">here</a>)<br>
<font face="Calibri"><br>
Processed phases, like those in a cross-spectral density array and
it's children like coherence, PLVs etc., will <i>not </i>be
different. You will only notice the difference if you choose
cfg.output = 'fourier'. <br>
<br>
The change will be latest version on our FTP-server tonight.<br>
