Hello,

I receive this denoising error during step 6/6, updating analysis variables : 

ERROR DESCRIPTION:

Index exceeds matrix dimensions.
Error in conn_process (line 1712)

I've examined my setup information to try and identify any missing information but have not been able to find anything. Any other ideas?

Thanks!

Hi William,

I am not exactly sure about this one, it may be an issue with the compatibility with older CONN projects, would you mind sending me your conn_*.mat file so that I can better diagnose this?

Thanks
Alfonso

Hey Alfonso,

Thank you for your reply. Attached is the conn_*.mat file as requested. Please let me know if you may need anything else. I'll work on it on my end as well.


Thanks,

Hello,

I am suffering from the same problem here. I am getting the same error as William mentioned and have tried running through older versions of CONN to no avail.  Strangely, I can run the denoising step if I do not select voxel-voxel options but I need these and when I include it breask down at the final stage. I was wondering if anyone could shed any further light on how to resolve this issue in denoising?

Many thanks,

Nick

Hi William&Nick,

Sorry about that. I believe this issue appears in some cases when updating projects older than 15.h to releases newer than 17.a (when there was a somewhat major update to the way we organize voxel-to-voxel analyses). In general, if you encounter this issue and do not have any voxel-to-voxel analyses defined in your project, or if you can live with simply repeating your existing voxel-to-voxel analyses after the update, then simply typing:

   conn('set','vvAnalyses.regressors',conn_v2v('empty'));
   conn_process denoising_finish;
   conn save;

after loading your project in any of the newer versions of CONN should fix this issue. 

If, on the other hand, you really would prefer to try keeping your existing voxel-to-voxel analyses, that requires a little of manual editing since it all depends a bit on the specificities of your existing project:

   @William: I have gone ahead and done those changes for the conn*.mat file that you provided (the modifications are in the attached file). Please let me know if you still run into any issues. With this you should be able to proceed normally and will still have access to your existing voxel-to-voxel analyses. The only limitation of this approach is that CONN will not allow you to add other/additional voxel-to-voxel analyses to this project

   @Nick and anybody else encountering this same issue: if you prefer to follow this route please send me your conn_*.mat file and I will be happy to take a closer look and make these changes

Best
Alfonso
