I really need to make this function. Unless amino acid metabolism models are available in any other database, I would like to troubleshoot these errors. For example, the very first error concerns cpdC00025*[Reaction cooperativity])-1)), which I read when I opened the block property editor for that reaction (reaction 117 of Model Browser). I have no idea what this error means. Is there something I could do to troubleshoot these incomprehensible errors? Thank you very much.
