Hi,
the easiest way to manage the user-defined library might be from within the Model Builder app:
That said, you can still modify a user-defined kinetic law programmatically with:
kl = sbioselect(sbioroot, Name='Uni-Uni MM reversible with e0',Type='abstract_kinetic_law');
kl.Expression = '<edit the expression here>'
If you want to remove an existing user-defined kinetic law programmatically that is already used in a model, you can do the following:
kl = sbioselect(sbioroot, Name='mylaw1',Type='abstract_kinetic_law');
% find reactions in model that use this kinetic law
reacObj = findUsages(kl, modelObj);
% set the kinetic law of these reaction to 'Unknown' but keeping the same reaction rates
% by reassigning the Reaction Rate to itself
arrayfun(@(x) set(x,'ReactionRate',x.Reaction.Rate), reacObj);
% remove kinetic law from library
sbioremovefromlibrary(kl)
Best regards,
Jérémy
