Checks if a certain study (given by its root folder) is conform with the [SFB standards](https://gitlab.ruhr-uni-bochum.de/sfb1280/studychecker/-/wikis/SFB-data-and-metadata-standards). This is achieved by checking the folder structure and all _meta.json_ files.
The following errors will be checked:
-*InconsitentModalityError*: Modalities change inbetween subject folder of the same session.
Checks if a certain study (given by its root folder) complies with [SFB standards](https://gitlab.ruhr-uni-bochum.de/sfb1280/studychecker/-/wikis/SFB-data-and-metadata-standards). This is achieved by checking the folder structure and validating all metadata files.
The SFB Study Checker detects the following errors and draws the user's attention to them:
-*InconsitentModalityError*: The modalities are inconsistent between subjects for one session.
-*InconsitentSessionError*: Amount of sessions varies from subject to subject.
-*IncorrectSubjectIDInMetaDataError*: Subject ID in meta.json differs from the subject folder name.
-*InvalidSessionNameError*: Naming convention of the session folder invalidated.
-*NoMetaDataInSubjectError*: The subject does not contain any meta.json files.
-*NoMetaDataLastLayerError*: On the lowest directory no meta.json file found.
-*NoSubjectError*: Study does not contain any subjects. Mostly because incorrect subject folder or subject prefix selected.
-*UnknownModalityError*: Modality folder name is not standard.
-*NoSubjectError*: Study does not contain any subjects. Please check, if the correct subject folders or subject prefix was selected selected.
-*UnknownModalityError*: Name of the modality folder is not contained in the [SFB metadata](https://gitlab.ruhr-uni-bochum.de/sfb1280/metaapp_2/-/wikis/MetaDataApp-Wiki/SFB-1280-metadata-fields#7-modality).
