.DMR File Extension

File created by BrainVoyager, a program used for analyzing MRI data of the brain; describes the brain imaging data but does not contain the data itself--the data is stored in one or more corresponding files (e.g., ".dwi" files or DICOM .DCM files); often used for concatenating multiple images into a sequenced image project.

NOTE: DMR stands for Diffusion-weighted Magnetic Resonance.
