Hi Tyler

this problem has already been solved by Jörn M. Horschig.
I attach here the answer he gave to me some time ago

Best regards
Sara

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
