[FieldTrip] problem occurs when using ft_timelockanalysis

["Jörn M. Horschig"]

Hi Sara,

I guess you are not using a mac. What you describe concerns bug 2452 on 
our Bugzilla page:
http://bugzilla.fcdonders.nl/show_bug.cgi?id=2452
which pertains to some undocumented change in Matlab. Therefore it is 
necessary to use a different mxserialize function that from matlab 2014a 
onwards  than before. This is a c++ function, which requires to be 
compiled for each platform independently. In FieldTrip, this file exists 
e.g. in fileio/private but only for MacOS 64-bit platforms. Apparently, 
we still need to compile it for MacOS 32bit, Windows and Linux 
platforms. I guess we should do that quite soon ;) I'll bring it up in 
today's FT meeting so that hopefully from tomorrow onwards it should work.

btw, for you it will help to go to the FieldTrip/src directory in Matlab 
and type
 >> mex mxSerialize_cpp.cpp

Then Matlab will mex (~compile) the file for you. You can then copy that 
file to your matlab code directory and everything should work out fine 
for you. I'll keep you updated on this.

Best,
Jörn
