Error: Output argument not assigned

Dear CONN team,

Thank you for your work on the latest version of CONN.

I receive the error below when using v17 to load data preprocessed from v16. There were no errors when using v16.

Were there any changes in the assignment of outputs in v17? Any assistance will be much appreciated.

Thanks,
Emmanuel

Dear Emmanuel,

Thanks for reporting this, that was in fact a bug in 17a when dealing with pre-2014a Matlab versions. This has been fixed in the new 17a release I have just uploaded. Please let me know if you run into any other issues.

Best
Alfonso

Thanks Alfonso, the above bug has been resolved. Another error surfaced at the denoising stage:

RE: Error: Output argument not assigned

Hi Emmanuel,

Thanks for reporting this. I am trying to replicate this issue, one way that I can do that is if I first use "save as" to rename a project, and then run the Denoising step (without first running the Setup step). Could you please let me know whether this is what happened in your case as well? If so, then simply re-running the setup and denosing step should fix this issue. When using "save as" to create a copy of your CONN project, only the project definitions are saved to your new project but none of the analysis files are replicated/transfered to the new project, so you typically need to re-run all CONN steps starting from Setup (I will modify the GUI to try to make it clearer what steps need to be re-run in this case). In any way, let me know if this scenario does not fit your case.

Hope this helps
Alfonso
