name	dpdata-cli
description	Convert and manipulate atomic simulation data formats using dpdata CLI. Use when converting between DFT/MD output formats (VASP, LAMMPS, QE, CP2K, Gaussian, ABACUS, etc.), preparing training data for DeePMD-kit, or working with DeePMD formats. Supports 50+ formats including deepmd/raw, deepmd/comp, deepmd/npy, deepmd/hdf5.
compatibility	Requires uvx (uv) for running dpdata

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

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