MethodError: objects of type SparseIdentificationResult are not callable

Line 235 in dd83689

z = Ψ([S/N,I,D/N]) # Exposure does not depend on exposed, removed, or cumulative!

I get this error when attempting to the function as it is
"MethodError: objects of type SparseIdentificationResult are not callable"

It seems you are using a newer version of DataDrivenDiffEq. The original script has been written with v0.1.4 in mind, but the SparseIdentificationResult has been introduced later.

Did you activate the env within the SEIR_exposure folder ?

i imagined something like that was the issue. I did not activate env, just went around by defining the Ψ function by hand using the found terms. Will have to check the updated way to do this.
