How to choose "elements" and "type_map"?

[Zhang-pchao]

In a run_param.json file, "type_map": ["C","H","O"]. If "sys_configs" contains structures composed of different elements such as "C", "HO", and "CHO", can the corresponding POTCAR be generated? (does it mean that you need to train separately, then merge all the training sets, and finally complete the training?)

[AnguseZhang]

Don't worry about "composed of different elements such as "C", "HO", and "CHO" " . DP-GEN can automatically handle this via type_map in dpdata, once you designate the correct correspondence bewteen type_map and potcars in param.json.
