[ATOM3D](https://www.atom3d.ai/) enables machine learning on three-dimensional molecular structure.

## Features

* Access to several datasets involving 3D molecular structure. 
* LMDB data format for storing lots of molecules (and associated metadata).
* Utilities for splitting/filtering data based on many criteria.

For more detailed information, [read the documentation](https://atom3d.readthedocs.io/en/latest/).

## Installation

Install with:

```
pip install atom3d
```
    
To use rdkit functionality, please install within conda:

```
conda create -n atom3d python=3.6 pip rdkit
conda activate atom3d
pip install atom3d
```

## Usage


### Downloading a dataset

From python:
```
import atom3d.datasets as da
da.download_dataset('lba', PATH_TO_DATASET) # Download LBA dataset.
```

Or, download and unzip from the [website](https://www.atom3d.ai/).

### Loading a dataset

From python:
```
import atom3d.datasets as da
dataset = da.load_dataset(PATH_TO_DATASET, {'lmdb','pdb','silent','sdf','xyz','xyz-gdb'})
print(len(dataset))  # Print length
print(dataset[0].keys())  # Print keys
```

### LMDB datasets

LMDB allows for compressed, fast, random access to your structures, all within a
single database.  Currently, we support creating LMDB datasets from PDB files, silent files, and xyz files.

#### Creating an LMDB dataset

From command line:
```
python -m atom3d.datasets PATH_TO_PDB_DIR PATH_TO_DATASET --filetype {pdb,silent,xyz,xyz-gdb} 
```

For more usage, please see the [documentation](https://atom3d.readthedocs.io/en/latest/).
