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.
The MRC file format is a standard for storing the results of cryo-electron microscopy (cryoEM) and electron tomography (ET). These techniques generate three-dimensional grids of voxels, each containing information about electron density or electric potential.
