Dear Alfonso,

I encounter a problem in the preprocessing step with the new toolbox. Here is the error:

Error using ==> cat
CAT arguments dimensions are not consistent.

Error in ==> conn_process at 1028
fbdataroi{ncondition}{length(X1{1}.data)+ncov}{nfb}=cat(1,fbdataroi{ncondition}{length(X1{1}.data)+ncov}{nfb},fby{nfb}(C{nses}.samples{ncondition},:,:));
Error in ==> conn_process at 16
case 'preprocessing_gui',disp(['CONN: RUNNING PREPROCESSING STEP']); conn_process([1.5,2,6:9],varargin{:});
Error in ==> conn at 1969
conn_process('preprocessing_gui');
Error in ==> conn_menumanager at 103
feval(MM.MENU{n0}.callback{n1}{1},MM.MENU{n0}.callback{n1}{2:end});

Many thanks for your help
Regards
