Resolve Subject Identifiers
The mental health research community has standardized the NDA GUID for cross-project subject identifiers. However, many other identifiers do remain in use by the research community. To resolve the appropriate GUID/subjectkey and ensure that no duplicate subjects exist in data retrieved from NDA, use this interface (single or multiple entries using the GUID Search Template).
If a match is not found, NDA has not yet received that subject identifier. To add subject identifier associations to NDA, include the subject identifier and submit to NDA using one of our Resolve Identifiers data structures (e.g. ndar_subject, genomics_subject). We will then resolve the identifiers for you within NDA allowing us to collectively fix duplicate subject identifiers that are used in different systems.
Note that NDA pseudoGUID promotions are automatically applied to the repository. If a source exists that we currently don't support, please contact us at the the NDA Help Desk so that we can add it.
The Autism Community has standardized on the NDA GUID for cross project subject identifiers. However, many other identifiers will remain in use by the research community. To resolve the appropriate GUID/Subjectkey for your identifiers and to ensure that no duplicate subjects exist in data retrieved from NDA, use the provided interface below (single or multiple entries using the GUID Search Template.)
If a match is not found, NDA has not yet received that subject identifier. To add subject identifier associations to NDA, include the subject identifier and submit into NDA using one of our Resolve Identifiers data structures (e.g. ndar_subject , genomics_subject ). NDA pseudo-GUID promotions are automatically applied to the repository. Once submitted and shared, you will receive all related subjects when using the nda.nih.gov query and download. If a source exists that we currently don’t support, please contact us at The NDA Help Desk.
For those using data in NDA contributed by others, please use this interface to determine if duplicate subject identifiers may exist.
