## Refine get started and input examples

Sometimes we want to refine the calculation of a property from previous results. For example, when higher convergence criteria `EDIFF` and `EDIFFG` are necessary in VASP, the new VASP calculation is desired to start from the previous output configuration, rather than starting from scratch.

An example of the input file `refine.json` is given below:

```json
{
  "structures": [
    "confs/std-*"
  ],
  "interaction": {
    "type": "deepmd",
    "model": "frozen_model.pb",
    "type_map": {
      "Al": 0
    }
  },
  "properties": [
    {
      "type": "vacancy",
      "init_from_suffix": "00",
      "output_suffix": "01",
      "cal_setting": {
        "input_prop": "lammps_input/lammps_high"
      }
    }
  ]
}
```

In this example, `refine` would output the results to `vacancy_01` based on the previous results in `vacancy_00` by using a different input commands file for lammps.
