How to load the multiple files by the "init_data_sys" in input.json of dpgen?

[Guancred]

Hi, there are many folders for my initial data, whether there a simple method for me to load these folders ? I have tried to set "*" in the dictionary of "init_data_sys" as following figure， but it does not work.

Thanks very much!

A directory that contains all of the data can be given. The data is found resrecursively.
