Sorry 🥲, I think we don't need any of the new extraction functions. Could you please show in an issue what you need/want to accomplish?

note that the collection (a DataFrame) is being done from here on:

EasyHybrid.jl/src/train.jl

Line 338 in 1736d03

# ? this could be saved to disk if needed for big sizes.

, for parameters, yes maybe we need some convenience functions. But, for DataFrames we could just show how use a normal filter for a DataFrame.
