Hello,

I was trying to perform a second level analysis in CONN recently.  CONN had been working fine a few months ago, but now (I suspect due to upgrading to MATLAB 2023a), I am getting the error message below:

ERROR DESCRIPTION:
 
Undefined function 'file2mat' for input arguments of type 'struct'.

Error in file_array/subsref>subfun (line 80)
t = file2mat(sobj,varargin{:});

Error in indexing (line 60)
 t = subfun(sobj,args{:});

Error in nifti/subsref>rec (line 219)
 t = subsref(t,subs(2:end));
