setting a function that requires modifiers, should map them if specified

[fbergmann]

When changing a function on a reaction, it should automatically add modifiers to the reaction scheme.

• currently, when a reaction r1 with scheme A -> B is assigned a kinetic using modifiers this fails

In the gui, this is allowed, however, this results in an invalid function, since no mapping is specified at that point. I would rather want to avoid creating invalid states, as it would be hard to track down later.

So i propose to silently add modifiers to the reaction scheme, iff a mapping for modifier to species is defined. that means:

• set_reaction('r1', function='function with modifier') would still fail, however
• set_reaction('r1', function='function with modifier', mapping={'formulaTokenUsedAsModifier', 'speciesName' }) would work

@pmendes would that work for you?

@fbergmann I think that is the best solution, thanks.
