The micrographs are scanning diffraction data collected on TEAM1 microscope at Lawrence Berkeley National Lab using a K2 direct electron detector. Each data set represents a 4 dimensional stack of data where the first 2 dimensions are the detector dimensions and the second two are the scan dimensions in real space.

Each .dm4 file contains a 4D stack of data with the following dimensions: 1792,1920,scanX,scanY
where the first two dimensions are the detector dimensions and the second two correspond to a real space scan. Each diffraction pattern corresponds to a single 2.5 ms exposure with a total accumulated dose of 1 electron per squared Angstrom.
