Use Case Name : ../TranscriptionInhibitionShorthand
For Feature : MIMEditor
<<TableOfContents: execution failed [Argument "maxdepth" must be an integer value, not ""] (see also the log)>>
A user wants to describe the possibility that one species can inhibit transcription of a protein, without showing in detail, all of the mechanisms.
Step-by-Step User Action
- User specifies a species as the inhibitor
- User specifies a transcription reaction to inhibit
User specifies that there is a ../TranscriptionInhibitionShorthand relationship between the two
- User optionally specifies the evidence for this reaction
The symbol for ../TranscriptionInhibitionShorthand follows:
An example showing A inhibiting the transcription of B follows:
There are two right angles near the head. This can be more clearly seen when there is a longer edge.
This use case differs from ../ShowInhibition in that the mechanism represented by ../TranscriptionInhibitionShorthand is inhibition of transcription, where as ../ShowInhibition can represent any mechanism of inhibition.
Requirements for Cytoscape
This has been used infrequently, and so is of a lower priority. ../ShowInhibition is usually sufficient.
BioPax representation TBD

can be handled by a new Edge type and associated rendering?
would require modifications to vizmapper for edge rendering, or custom edge graphics?

Actually, since the bend is hear the head of the target node, couldn't we just support it with a new type of arrowhead? Or is it best handled as an edge with anchor points and right-angle constraints?
