It now looks like you edited every single line in the file. Did the line endings change?

https://github.com/ReactionMechanismGenerator/RMG-database/commit/22c2ec91f2be4ca5d878034f3f0df6f14b958c7e

This is still a problem (see https://github.com/ReactionMechanismGenerator/RMG-Py/issues/2490#issuecomment-1603094355 )

This looks helpful, and indeed necessary for https://github.com/ReactionMechanismGenerator/RMG-Py/pull/2321. What would be some suitable unit tests? Can we go in both directions (to and from Cantera) allowing round-trip testing? Else I...

Just built a model using these commits, which resulted in a declared duplicate not being found: ``` *********************************************************************** CanteraError thrown by Kinetics::checkDuplicates: No duplicate found for declared duplicate reaction number...

The problem with things being declared as duplicates that aren't, was indeed an error in the NOx2018 library. This is addressed in https://github.com/ReactionMechanismGenerator/RMG-database/pull/377 but we should probably still add checks...

Note that although I think this fixes a problem that we had in identifying the duplicate reactions and labeling them as such for valid chemkin files, it does not address...

How does it behave in the latest ck2yaml? Same?

Worth keeping alive and merging??
