inferred from direct assay
evidence_code2.obo
IDA
Used to indicate a direct assay was carried out to determine the function, process, or component indicated by the GO term. Curators therefore need to be careful, because an experiment considered as a direct assay for a term from one ontology may be a different kind of evidence for a term from another of the ontologies. In particular, there are more kinds of direct assays for cellular component than for function or process. For example, a fractionation experiment might provide "direct assay" evidence that a gene product is in the nucleus, but "protein interaction" (IPI) evidence for its function or process.

EXP
Used in an annotation to indicate that an experimental assay has been located the cited reference, whose results indicate a gene product's function, process involvement, or subcellular location (indicated by the GO term). The IE code is the parent code for the IDA, IMP, IGI, IEP and IPIexperimental codes. The IE evidence code can be used where any of the assays described for the IDA, IMP, IGI, IPI or IEP evidence codes is reported. However it is highly encouraged that groups should annotate to one of the more granular experimental codes (IDA, IMP, IGI, IPI or IEP ) instead of IE, and all curators directly involved in the GO Reference Genome annotation effort are obliged to use these and not IE. The IE code exists for groups who would like to contribute high-quality GO annotations that are produced from directly associating GO terms to gene products by citing experimental published results, but where the group is unable to fit the appropriate specific experimental GO evidence codes to each annotation.

IEA
Used for annotations that depend directly on computation or automated transfer of annotations from a database, particularly when the analysis is performed internally and not published. A key feature that distinguishes this evidence code from others is that it is not made by a curator; use IEA when no curator has checked the specific annotation to verify its accuracy.

IMP
The IMP evidence code covers those cases when the function, process or cellular localization of a gene product is inferred based on differences in the function, process, or cellular localization between two different alleles of the corresponding gene. The IMP code is used for cases where one allele may be designated 'wild-type' and another as 'mutant'. It is also used in cases where allelic variation occurs naturally and no specific allele is designated as wild-type or mutant. Caution should be used when making annotations from gain-of-function mutations as it may be difficult to infer a gene's normal function from a gain of function mutation, although it is sometimes possible.

traceable author statement
evidence_code2.obo
The TAS evidence code covers author statements that are attributed to a cited source. Typically this type of information comes from review articles. Material from the introductions and discussion sections of non-review papers may also be suitable if another reference is cited as the source of experimental work or analysis. When annotating with this code the curator should use caution and be aware that authors often cite papers dealing with experiments that were performed in organisms different from the one being discussed in the paper at hand. Thus a problem with the TAS code is that it may turn out from following up the references in the paper that no experiments were performed on the gene in the organism actually being characterized in the primary paper. For this reason we recommend (when time and resources allow) that curators track down the cited paper and annotate directly from the experimental paper using the appropriate experimental evidence code. When this is not possible and it is necessary to annotate from reviews, the TAS code is the appropriate code to use for statements that are associated with a cited reference. Once an annotation has been made to a given term using an experimental evidence code, we recommend removing any annotations made to the same term using the TAS evidence code.

Use of the ND evidence code indicates that the annotator at the contributing database found no information that allowed making an annotation to any term indicating specific knowledge from the ontology in question (molecular function, biological process, or cellular component) as of the date indicated. This code should be used only for annotations to the root terms, molecular function ; GO:0003674, biological process ; GO:0008150, or cellular component ; GO:0005575, which, when used in annotations, indicate that no knowledge is available about a gene product in that aspect of GO.

Used when an annotation is made based on the analysis of a biochemical aspect of a mutant phenotype; for example, the accumulation of a biosynthetic intermediate.

IMP: analysis of biochemical trait
inferred from physiological response
evidence_code2.obo
Used when an annotation is made based on the physiological response of a mutant to an external stimulus; for example, abnormal growth of the root in response to gravity, delay in flowering in response to varying light conditions.

inferred from visible phenotype
evidence_code2.obo
Used when an annotation is made based on the visual examination of a mutant phenotype; for example, abnormalities in organism morphology.

inferred from genomic context
evidence_code2.obo
Used whenever information about the genomic context of a gene product forms part of the evidence for a particular annotation. Genomic context includes, but is not limited to, such things as identity of the genes neighboring the gene product in question (i.e. synteny), operon structure, and phylogenetic or other whole genome analysis.
