pytng 0.2.2

Minimal Cython wrapper of the TNG trajectory library

This package provides the TNGFileIterator object to allow simple Pythonic access to data contained within TNG files.

import pytng
import numpy as np

with pytng.TNGFileIterator('traj.tng', 'r') as tng:

  positions = np.empty(shape=(tng.n_atoms,3), dtype=np.float32)

  for ts in tng:
    time = ts.get_time()
    positions = ts.get_positions(positions)

This package contains Python bindings to libtng for TNG file format[1] [2]. This is used by molecular simulation programs such as Gromacs for storing the topology and results from molecular dynamics simulations.

Warning

This package is under active development. The API is liable to change between release versions.
