How to match train and test set atom order

[ankitmathanker]

When trying to create a dpdata train and test set for a system with 4 atom type Pt, C, H, O, I see that atoms order in training set is PtCHO whereas the test set is of order OHCPt. Is there a way for me to specify the ordering so that both train and test set have same order of atoms.

It is not necessary to impose the same order in deepmd training and test data, if the type_maps for both datasets are set correctly.
