Homology Propagation Statistics

Homology Propagation Statistics

Generated 2026-09-26 by just propagation-stats from the cached GOA
files under genes/ (donor cache refreshed 2026-09-26).
Counts cover every gene with a cached GOA file. The unit is one annotation
(gene, term, evidence, reference, negation): pipelines that emit one GOA line
per donor, or split one annotation across qualifiers, are merged
(35,045 GOA lines → 34,265 annotations).
Reviewed annotations are those matched to an existing_annotations entry
with a final review action.
These numbers are regenerated; do not copy them into project prose.

ISO: does the donor still carry the term?

Donor support is the donor's current evidence for the exact transferred term
(QuickGO). INFERRED_ONLY means the donor itself only has inferred support —
typically a transfer of a transfer. ABSENT means the donor was checked and no
longer carries the term.

ISO: donor symbol vs target symbol

A different donor symbol flags paralog or multi-locus sourcing (for example rat
Calm1/Calm2 as donors for mouse Calm3). MIXED means the annotation has both a
namesake donor and a differently named one. It prompts a check; it is not a verdict.

What does ISO add on top of IBA?

For each ISO annotation, the closest IBA annotation on the same target (GO is_a/part_of
closure). Annotations in the first two buckets are already implied by PAINT; the last two
are what ISO contributes beyond IBA.

IBA on target biological_process cellular_component molecular_function All ISO Share
IBA to the same term 190 197 199 586 14%
IBA to a more specific term (already entails the ISO annotation) 95 81 88 264 6%
IBA only to a more general term (ISO adds specificity) 144 174 64 382 9%
No related IBA (ISO adds a new assertion) 1825 552 623 3000 71%
