IJC chemical terms for reactants/products in reaction tables

While I'm quite familiar with using and constructing chemical terms in "molecule" tables in IJC, I am struggling to get similar terms to work on structures inside reactions in "reaction" tables





Commands such as those found in your online guide:

e.g.





mass(product(1))





..are not valid





Do I need to define reactants/products somehow or map atoms in Marvin when the reaction is drawn to be able to call them in a chemical term?





Perhaps these kinds of calculations are only a feature of JChem proper or requires a license?





Thanks for your help,

Reaction context examples work only if the evaluation environment of the Chemical Terms expression is reaction context. Currently reaction context is used only in Reactor. We will consider using reaction context also with reaction tables.
