If you rely on this specific functionality of freqdescriptives I
would advice you to copy the old version into your fieldtrip-folder.
There are indeed some bugs in the more recent versions of
freqdescriptives which have been introduced along the way, but I (and
others) did not yet find time to fix it. We anyway hope to soon move
to a new implementation of freqdescriptives, which does not seem to
make the patching worthwile.

The aim of this list is to facilitate the discussion between users of the FieldTrip toolbox, to share experiences and to discuss new ideas for MEG and EEG analysis. See also http://listserv.surfnet.nl/archives/fieldtrip.html and http://www.ru.nl/neuroimaging/fieldtrip.
