:ref:`Format description <ripple-file_specification>` for the :ref:`ripple
<ripple-format>` file format.


MRC (CCP-EM)
------------

The :ref:`MRC <mrc-format>` file format is a standard open file format for electron microscopy data and is
defined by  `Cheng et al <https://doi.org/10.1016/j.jsb.2015.04.002>`_. The file format is described in
detail following the link as well:  `MRC2014 <https://www.ccpem.ac.uk/mrc_format/mrc2014.php>`_.

Additionally Direct Electron saves a couple of files along with the ``.mrc`` file. In general, the file naming
scheme is CurrentDate_MovieNumber_suffix_movie.mrc with the metadata file named CurrentDate_MovieNumber_suffix_info.txt.
and different external detectors or virtual images are saved as CurrentDate_MovieNumber_suffix_ext#_extName.mrc or
CurrentDate_MovieNumber_suffix_#_virtualName.mrc respectively. The suffix is optional and can be any
string or left empty. By default Virtual image 0 is the sum at each navigation point and is equivalent to the
navigation image.
