MRC (file format)

Not to be confused with mixed raster content or MARC standards.

MRC is a file format that has become an industry standard in cryo-electron microscopy (cryoEM) and electron tomography (ET), where the result of the technique is a three-dimensional grid of voxels each with a value corresponding to electron density or electric potential. It was developed by the MRC (Medical Research Council, UK) Laboratory of Molecular Biology.^[1] In 2014, the format was standardised.^[2] The format specification is available on the CCP-EM website.
