# python-gsd

GSD (General Simulation Data) is a file format specification and a library
to read and write it. The package also contains a python module that reads
and writes hoomd schema gsd files with an easy to use syntax.

* Efficiently store many frames of data from simulation runs.
* High performance file read and write.
* Support arbitrary chunks of data in each frame (position, orientation,
  type, etc...).
* Append frames to an existing file with a monotonically increasing frame
  number.
* Resilient to job kills.
* Variable number of named chunks in each frame.
* Variable size of chunks in each frame.
* Each chunk identifies data type.
* Common use cases: NxM arrays in double, float, int, char types.
* Generic use case: binary blob of N bytes.
* Easy to integrate into other tools with python, or a C API (< 1k lines).
* Fast random access to frames.
