MATLAB 2011a to MATLAB 2013

I have an older version of MATLAB (2011) because that is what our University uses but am trying to use a script from 2013 MATLAB and continually get the same error:

??? Undefined function or method 'eq' for input arguments of

type 'cell'.

Error in ==> fullfile at 39

elseif (f(end)==fs) || (part(1)==fs || (bIsPC &&

(f(end)=='/' || part(1)=='/')) )

Error in ==> firstlevelanalysis_estimate_BITREC1 at 16

tmp=fullfile(subfatherdir,subsname(s),tp(1),session(1),'swau*');tmp=dir(tmp{1});

Is there a way to make this script compatible?

Possibly

 tmp = fullfile(subfatherdir, subsname{s}, tp{1}, session{1} ,'swau*');
  tmp = dir(tmp) ;
