Information from the DIAGRAM-INFO slot
I'm interested in how pathway-tools lays out the reactions in the pathway diagrams. My little bit of consulting Prof. Google tells me that Grasper-CL was used in generating the layout. And I can see this in the ocelot databases concerning the DIAGRAM-INFO slot:
This slot contains an s-expression comprising a structured description of the pathway diagram. This information is a list in the following format:
(((entity-node entity-frame x y wd ht (ftr angle text)))
((rxn-node rxn-frame x y (reactant-node) (product-node) reversible?
((rct-or-prod-node (x y))) curve-left curve-right))
((control-frame controller-node controlled-node ((x y))))
((membrane-shape label label-x label-y x y wd ht cco-frame))
((non-frame-node-type x y wd ht text)*)
)
But I'm having trouble finding information from this slot in my (limited ability) lisp queries. Is there a call to retrieve this information? Or, alternately, is Grasper-CL part of the toolkit for pathway-tools, or a separate license?
Thanks
