[Eeglablist] warnings

[Joseph Dien]

This is just a problem with the Biosig package that's included in the  
Fieldtrip package that is included with EEGlab.  Biosig took the  
unfortunate approach of replacing some of Matlab's built-in functions  
with customized versions (apparently they wanted to change how they  
handle NaN).  Not really a problem since they're in a "private" folder  
and hence don't affect functions outside of Biosig but they still trip  
off Matlab warnings.  FieldTrip just announced they're dropping the  
Biosig package due to concerns about the warning messages so it no  
longer includes the Biosig package.  If you download the latest  
version of FieldTrip (http://fieldtrip.fcdonders.nl/) and replace the  
version that came with EEGlab (in it's "external folder") it  
eliminates the warnings (and give you the latest bugfixes and  
features).  You would need to redo the path since the FieldTrip folder  
would have a new name.  Of course, dropping Biosig also means losing  
its support for .edf format files and so forth.  It would probably be  
a good idea for EEGlab to update its copy of FieldTrip too to avoid  
eliciting these concerns.

Cheers!

Joe
