Hi there,

I'm a new user of Conn. Lovely toolbox, btw. I am having a pretty regular problem with the 2nd level analysis function tho. Whenever I push DONE and wait for the 2nd level analysis to run, I get this error message:

??? Reference to non-existent field 'csources'.

Error in ==> conn_process at 1465
                    csources=SPMall(n1).connvols.csources;

Error in ==> conn_process at 18
        case 'results',         conn_process(14:15,varargin{:});

Error in ==> conn at 1601
                conn_process('results');

Error in ==> conn_menumanager at 112
feval(MM.MENU{n0}.callback{n1}{1},MM.MENU{n0}.callback{n1}{2:end});
 
??? Error while evaluating figure WindowButtonUpFcnAny help would be greatly appreciated.mac

Hi Mac,
 
You would need to select a 'random-effects' model (instead of 'fixed-effects' model) in the second-level results window to be able to run these analyses (currently fixed-effects second-level analyses are only partially implemented as a simple way to look at single-subject data, but most of the second-level results, including the 'whole-brain' displays and 'done' options, are only implemented for random-effect analyses)
 
Hope this helps

Hi,

I agree this is a great tool. I get that error when I do the fixed effects as well but i also get an error for the random effects:

??? Reference to non-existent field 'iB'.

Error in ==> spm_spm at 453
    iX0    = [SPM.xX.iB SPM.xX.iG];

Error in ==> conn_process at 1484
                    SPM=spm_spm(SPM);

Error in ==> conn_process at 20
        case 'results',         conn_process(14:15,varargin{:});

Error in ==> conn at 1643
                conn_process('results');

Error in ==> conn_menumanager at 112
feval(MM.MENU{n0}.callback{n1}{1},MM.MENU{n0}.callback{n1}{2:end}); 
??? Error while evaluating figure WindowButtonUpFc

Any ideas?

Thanks,
Andy

Hi Andy,
 
Sorry about that, that 'iB' error is associated with some recent modification in SPM8, could you try the attached conn_process.m file (simply save this file into your conn distribution folder overwriting the file with the same name) and let me know whether that seems to fix this issue?

Thanks. That worked.
