The terms describing the data stored in the network of AIRR-seq repositories federated by the iReceptor Gateway are driven by the recommendations of the AIRR Community: the AIRR Minimal Standards (MiAIRR) for study metadata and the AIRR Rearrangement schema representing annotated rearrangements. For more information, visit the AIRR Community documentation page.
The definitions and relevant examples for each field are given below:

| Sample Processing ID | Identifier to the sample processing object in the repertoire metadata for this rearrangement. If the repertoire has a single sample then this field may be empty or missing.

| Sequence ID | Unique query sequence identifier for the Rearrangement. Most often this will be the input sequence header or a substring thereof, but may also be a custom identifier defined by the tool in cases where query sequences have been combined in some fashion prior to alignment.
