dpdata CLI
dpdata is a tool for manipulating multiple atomic simulation data formats. This skill enables format conversion between various DFT/MD software outputs via command line.
Quick Start
Run dpdata via uvx:
uvx dpdata <from_file> [options]
Command Line Usage
dpdata: Manipulating multiple atomic simulation data formats
usage: dpdata [-h] [--to_file TO_FILE] [--from_format FROM_FORMAT]
[--to_format TO_FORMAT] [--no-labeled] [--multi]
[--type-map TYPE_MAP [TYPE_MAP ...]] [--version]
from_file
Arguments
| Argument | Description |
|---|
from_file | Read data from a file (positional) |
--to_file, -O | Dump data to a file |
--from_format, -i | Format of from_file (default: "auto") |
--to_format, -o | Format of to_file |
--no-labeled, -n | Labels aren't provided (default: False) |
--multi, -m | System contains multiple directories (default: False) |
--type-map, -t | Type map for atom types |
--version | Show dpdata version and exit |
Common Examples
Convert VASP OUTCAR to deepmd format
uvx dpdata OUTCAR -i vasp/outcar -O deepmd_data -o deepmd/raw
Convert LAMMPS dump to VASP POSCAR
uvx dpdata dump.lammps -i lammps/dump -O POSCAR -o vasp/poscar
Convert with type map
uvx dpdata OUTCAR -i vasp/outcar -O deepmd_data -o deepmd/raw -t C H O N
Convert multiple systems
uvx dpdata data_dir -i vasp/outcar -O output_dir -o deepmd/comp --multi
Convert to deepmd/npy (compressed format)
uvx dpdata OUTCAR -i vasp/outcar -O deepmd_npy -o deepmd/npy
Convert to deepmd/hdf5
uvx dpdata OUTCAR -i vasp/outcar -O data.h5 -o deepmd/hdf5

Tips
- Auto-detection: Use
-i auto (default) to let dpdata detect format automatically
- Type mapping: Use
-t to specify atom type order for deepmd formats
- Multi-system: Use
--multi for directories containing multiple systems
- Compressed output: Use
deepmd/npy or deepmd/hdf5 for smaller file sizes
