MRCZ format
-----------
.. note::
To read this format, the optional dependencies ``blosc`` and ``mrcz`` are
required.
The ``mrcz`` format is an extension of the CCP-EM MRC2014 file format.
`CCP-EM MRC2014 <https://www.ccpem.ac.uk/mrc_format/mrc2014.php>`_ file format.
It uses the `blosc` meta-compression library to bitshuffle and compress files in
a blocked, multi-threaded environment. The supported data types are ``float32``,
``int8``, ``uint16``, ``int16`` and ``complex64``.
It supports arbitrary meta-data, which is serialized into JSON.
MRCZ also supports asynchronous reads and writes.

the `mrcz` library needs to be installed and optionally `blosc` to use
compression.
