TNG (Trajectory Next Generation)
TNG (The Next Generation) is a highly flexible and high performance trajectory file format for molecular simulations, particularly designed for GROMACS. It includes support for storing both reduced precision coordinates and a lossless, full precision version simultaneously. This enables high quality scientific analysis alongside long term storage in a format that retains full scientific integrity. TNG supports an arbitrary number of data blocks of various types to be added to the file.
MDAnalysis supports reading of TNG files. The TNGReader uses the GROMACS tng library for reading the binary TNG format.
The TNG format includes high level C-style API functions for increased ease of use.
