Hi again,
 
I have installed the matlab 7.0, using conn 12.1. I'm still stuck at the preprocessing stage. I have inserted three confounds (white matter, CSF, with 0 derivatives and 5 dimensions) and realign parameters (rp file from the realign, 1 derivative, 6 dimensions). band-pass filter 0.01-0.08.
 
This error appears:
??? Error using ==> cat
Out of memory. Type HELP MEMORY for your options.
Error in ==> conn_process at 550
                B=cat(2,B,Bb);
Error in ==> conn_process at 12
        case 'preprocessing_gui',disp(['CONN: RUNNING PREPROCESSING STEP']); conn_process([6:8],varargin{:});
Error in ==> conn at 1071
   conn_process('preprocessing_gui');
Error in ==> conn_menumanager at 112
       feval(MM.MENU{n0}.callback{n1}{1},MM.MENU{n0}.callback{n1}{2:end});
??? Error while evaluating figure WindowButtonUpFcn.
 
I'm not sure if there is something in the setuo that is also wrong, particularly when defining conditions, which is resting-state: onset 0, and duration 600 seconds.
 
I'm really stuck!
Thank you in adavnce!
