Since the latter is more likely to be updated as things change in MTK.

I am new to Julia, so maybe I am overseeing an important point here. I am trying to fit parameters to multiple experiments. Fitting it to one set of experimental...

question

https://github.com/SciML/Catalyst.jl/pull/1070 disabled StructuralIdentifiability tests and added a warning in the docs about it having issues. Once they are resolved we should reenable the tests.

bug

`BifurcationProblem` does not support symbolic indexing and as a result, MTK (somewhat hackily) just removes `sys.index_cache` in the `BifurcationProblem` constructor to force `split = false` behavior. However, with `complete` now...

```julia rn1 = @reaction_network rn_observed begin @variables X1(t) @observables X2(t) ~ X1(t) k, A --> 0 end ``` when expanded gives ```julia :(Catalyst.complete(begin var"#7616#t" = Catalyst.default_t() begin var"#7617###1945" = begin...

bug

Since tests are now passing and I am not that familiar with the code, I haven't updated any spatial related codes to remove scalarization of parameters in https://github.com/SciML/Catalyst.jl/pull/1052. This should...

```julia ┌ Warning: Initialization system is overdetermined. 1 equations for 0 unknowns. Initialization will default to using least squares. To suppress this warning pass warn_initialize_determined = false. To make this...

bug

We should drop our test dependencies on OrdinaryDiffEq and switch to the slimmer packages for solvers we actually use there (mainly Tsit5 I think). This should help reduce build times...

bug
high priority

It seems like some users, especially anyone with a longer model, may prefer to have the DSL require all species, parameters, and variables to be pre-declared (to help with catching...
