The No Data (ND) evidence code should be used for annotations to the root nodes only and should be accompanied with GO_REF:0000015 or an internal reference. PMIDs cannot be used for annotations made with ND.
- if you are using an internal reference, that reference ID should be listed as an external accession for GO_REF:0000015. Please add (or email) your internal reference ID for GO_REF:0000015.
- All ND annotations made with a reference other than GO_REF:0000015 (or an equivalent internal reference that is listed as external accession for GO_REF:0000015) should be filtered out of the GAF.
The SQL code identifies all ND annotations that do not use GO_REF:0000015 or one of the alternative internal references listed for it in the GO references file.
