<font face="Calibri">Hello everybody!<br>
<br>
As of today, we have switched to a new implementation for the
'wltconvol' method for frequency analysis, and it has also been
renamed to 'wavelet'. For a while now we have been rewriting the
low-level code in a different format, one that is more flexible to
adapt in the future and that allows for the low-level algorithms
to be downloaded in a separate module: <i>specest</i>. The
changes will be on our ftp-server by tonight. <br>
<br>
The switch to the new implementation brings about several changes.
With respect to the changes are observable to the end-user, there
are several FAQs created at our wiki. <br>
<br>
For the end-user observable changes for 'wavelet' (formerly
'wltconvol'), please have a look <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"><i>here</i></a>,
and for a bigger description with respect to your output.freq
please go <a
href="http://fieldtrip.fcdonders.nl/faq/why_does_my_output.freq_not_match_my_cfg.foi_when_using_wavelet_formerly_wltconvol_in_ft_freqanalyis"><i>here</i></a>.<br>
<br>
</font><font face="Calibri"></font><font face="Calibri"><br>
Because of these changes, we strongly advise to either use the new
or the old implementation for your entire analysis project. The
old implementation is still available by using 'wltconvol_old' as
cfg.method (however, this code no longer being updated). You can
call also call the function: ft_freqanalysis_old, which is the old
interface-function.<br>
<br>
If you are interested, you can track the progress of the <i>specest
</i>module by going <a
href="http://fieldtrip.fcdonders.nl/development/specest"><i>here</i></a>.
As soon as the other low-level functions are ready and
implemented, another e-mail will be sent to the mailing-list.<br>
<br>
If anything is unclear, or if there are any bugs that have slipped
through our fingers, please send an e-mail to the mailing-list
and/or report a bug in our <i><a
href="http://fieldtrip.fcdonders.nl/bugzilla">Bugzilla bug
tracking system</a></i>.<br>

Kind regards,<br>
