By field
13 fields| Field | Changes | Written by | Latest note |
|---|---|---|---|
| properties | 4 | enrich_references, rdkit_post_consensus, rdkit_pre_consensus, withhold_ambiguous_mass | withhold_ambiguous_mass: removed molecular_mass, monoisotopic_mass; the flow carries 2 candidate structures, so no one mass describes it |
| altLabel | 2 | consensus_match, strip_catalogue_altlabels | Removed 2 catalogue altLabel value(s): 'IP 1620R' (grade code), 'NAS 3' (grade code) |
