# GSD

The **GSD** file format is the native file format for [HOOMD-blue](https://glotzerlab.engin.umich.edu/hoomd-blue/).
**GSD** files store trajectories of the **HOOMD-blue** system state in a binary file with efficient random access to
frames. **GSD** allows all particle and topology properties to vary from one frame to the next. Use the **GSD** Python
API to specify the initial condition for a **HOOMD-blue** simulation or analyze trajectory output with a script. Read a
**GSD** trajectory with a visualization tool to explore the behavior of the simulation.

## HOOMD examples

Create a hoomd gsd file.
```python
>>> s = gsd.hoomd.Frame()
>>> s.particles.N = 4
>>> s.particles.types = ['A', 'B']
>>> s.particles.typeid = [0,0,1,1]
>>> s.particles.position = [[0,0,0],[1,1,1], [-1,-1,-1], [1,-1,-1]]
>>> s.configuration.box = [3, 3, 3, 0, 0, 0]
>>> traj = gsd.hoomd.open(name='test.gsd', mode='wb')
>>> traj.append(s)
```

Append frames to a gsd file:
```python
>>> def create_frame(i):
...     s = gsd.hoomd.Frame();
...     s.configuration.step = i;
...     s.particles.N = 4+i;
...     s.particles.position = numpy.random.random(size=(4+i,3))
...     return s;
>>> with gsd.hoomd.open('test.gsd', 'ab') as t:
...     t.extend( (create_frame(i) for i in range(10)) )
...     print(len(t))
11
```

Randomly index frames:
```python
>>> with gsd.hoomd.open('test.gsd', 'rb') as t:
...     frame = t[5]
...     print(frame.configuration.step)
4
...     print(frame.particles.N)
8
...     print(frame.particles.position)

```

Slice frames:
```python

...     for s in t[5:-2]:
...         print(s.configuration.step, end=' ')
4 5 6 7
```

## File layer examples

```python
with gsd.fl.open(name='file.gsd', mode='wb') as f:
    f.write_chunk(name='position', data=numpy.array([[1,2,3],[4,5,6]], dtype=numpy.float32));
    f.write_chunk(name='angle', data=numpy.array([0, 1], dtype=numpy.float32));
    f.write_chunk(name='box', data=numpy.array([10, 10, 10], dtype=numpy.float32));
    f.end_frame()
```

```python
with gsd.fl.open(name='file.gsd', mode='rb') as f:
    for i in range(1,f.nframes):
        position = f.read_chunk(frame=i, name='position');
        do_something(position);
```
