MImerge accesses these three fields to identify cross-references, which could potentially identify molecules with different identifiers but describing the same entity.
The de-identified exception contemplates the removal of 18 different identifiers which removes any potential of re-identification.
Among these ion channels and transporters, 14 of them were likely to have isoforms in FW and SW as they have different identifiers when BLASTX to NCBI Human non-redundant database suggesting minor sequence difference between the isoforms although they were mapped to similar human gene symbols by IPA.
While the commercial browsers' DRM assigns unique identifiers to users that can be used to spy on viewing habits across multiple video providers and sessions, the Mozilla DRM uses different identifiers for different services.
A good system has distinct identifiers for each of these roles, and in fact, sophisticated ones could/should allow multiple different identifiers of the same functional class, for the same user, such as allowing an individual to have multiple characters on WoW, Iain Henderson calls this aspect of identity "personnas".
These are anonymous nodes that can assume different identifiers between versions.
The relationship between the different identifiers is illustrated diagrammatically in Fig. 1.
In fact, represents the interval, so an affine form describes a numerical domain in terms of a central value and a sum of intervals with different identifiers.
Also, the tautomers, which are most often presumed to be associated with the same substance (unless otherwise explicitly intended), are often labeled with different identifiers.
However, this means that blank nodes with different identifiers cannot be mapped, even if they represent the same element in different versions.
Note that, although multiple assays may be performed against an identical protein sequence, the assay-target association information deposited in PubChem may not be identical, because the target sequence can have multiple different identifiers [e.g., the same protein with different GI numbers (NCBI sequence identifier) and potentially from different organisms].
