Hi,

Has anyone encountered a similar error to below with the validator? I figured out this is related to the events files, but I used the same events files before without any issues. So what can go wrong here?

You should define 'HEDVersion' for this file. If you don't provide this information, the HED validation will use the latest version available.

Any clue would be much appreciated.

Thank you.

Best regards,

I have had a similar issue in some tests I run where one of my test dataset is not valid anymore.

I need to investigate but maybe try adding a HEDVersion metadata in your dataset description: Modality agnostic files - Brain Imaging Data Structure v1.9.0-dev
