Hi all,

I'm using CONN version 2020b, and am getting the following error when I try to run second-level analyses: 

ERROR DESCRIPTION:

Dot indexing is not supported for variables of this type.
Error in conn (line 10863)
SPM.xX_multivariate.statsname=info.statsname;
Error in conn_menumanager (line 135)
feval(CONN_MM.MENU{n0}.callback2{n1}{1},CONN_MM.MENU{n0}.callback2{n1}{2:end});
CONN20.b

My second level covariates are all arrays, so I'm not sure how to resolve this error.  Would really appreciate any insight!  Thanks.

I am experiencing this same issue and wondered if you ever found a solution?

Best, 

Eric

Hi Eric,

Sorry about this, I am trying to replicate this error condition, could you please check in your second-level results folder, where there will be a file named "spmF_mv.nii", whether another file named "spmF_mv.json" also exists, and if so, could you please send me that file to see if that helps me figure out what the issue might be here?

Thanks
Alfonso

Could you help me?
Thanks

Same error here.

Hi Alfonso,
I am also experiencing this same error. It occurs when I am in 2nd level ICA. I select AllSubjects, then a second level covariate and when I switch the Between-subjects contrast to Effect of second level covariate, this error pops up. It then hangs when I attempt to stop the process. There is a file named 'spmF_mv.json' in the results folder. I am attaching that here to assist finding the issue (unless you have already resolved this and I'm just not seeing the response in the forum). 
Thanks! Jennifer

I am experiencing the same issue. Any ideas on how to fix it?

Hi Sneha,

Could you please try one of the following possible fixes:

1) installing the attached patch (this patch is for version 20b, to install simply copy the attached file to your conn distribution folder overwriting the file with the same name there)

2) updating SPM12 to the latest release 7771 (e.g. running "spm_update update" in Matlab's command-line)

3) update CONN to the current development version (see http://www.conn-toolbox.org/resources/so...)

Please let me know if you still run into this issue

Hi Alfonso, 
Thanks for the answer. 
I tried the patch and I am still having the issue. Should I try the other options too?
Regards,

Hi Alfonso, 
I have tried the solutions you proposed, but I am still having this issue. For 1 and 2, nothing happens, the error message still appears. And, when I downloaded the CONN development version, spm stopped working.  
I am using Matlab 2016a, for student use. 
Could you please suggest another possible solution?
Thanks
Indi

Hi Everyone,

I ran into the same issue when using MATLAB R2021a + CONN 20b.

The proposed solutions did not work for me, however, I was able to resolve this by reverting to CONN 19c.

Hope this helps!

Thank you so much! Yes, it seems to work using 19c. But I am concerned because I got a warning message about incompatibility issue as my project was created using the 20. Do you think I should care?
Also, Do you know if the original error message ("Struct contents reference from a non-struct array object") is a real problem? Because I can perform the analysis just ignoring the error hahaha but no sure how ok is that.  

Thanks for the solution, you were very kind!

Hi
This should be fixed/working in the latest versions (currently 21a). Please let me know otherwise
Best

How did you revert back to the older version? Were there compatibility issues after opening with the older version?

Thank you,
