@antotorov do you still have the issue with v1.7.2? PET validation should be much better now compared to when you ran into the error with v 1.6.2.

it's possible that all that's needed is an edit of https://github.com/bids-standard/bids-validator/blob/master/bids-validator/bids_validator/rules/top_level_rules.json -- so I think if you are keen, you could look into that?

The bids-validator currently contains a check for the `IntendedFor` field as part of the NIfTI validation: https://github.com/bids-standard/bids-validator/blob/4feb91b8aa9506c123d38327485dd5d4cd69e80b/bids-validator/validators/nifti/nii.js#L1247-L1265 This leads to issues during validation with BIDS URIs, see this bids-examples PR:...

Actually, a check for this is in place here: https://github.com/bids-standard/bids-validator/blob/b542235df3579ed1328058ad41777c5dd96d2d73/bids-validator/validators/bids/fullTest.js#L163-L169 using this function: https://github.com/bids-standard/bids-validator/blob/b542235df3579ed1328058ad41777c5dd96d2d73/bids-validator/validators/bids/subjects.js#L1-L62 and this issue code: https://github.com/bids-standard/bids-validator/blob/b542235df3579ed1328058ad41777c5dd96d2d73/bids-validator/utils/issues/list.js#L273-L277 the question is ... why is it not triggered? Any idea...
