Where does the data come from?


EMPIAR stores and provides access to data from cryo-electron microscopy experiments performed in laboratories around the world. In addition to EMDB-related raw image data, Serial Block-Face Scanning Electron Microscopy (SBF-SEM) and Focussed Ion Beam Scanning Electron Microscopy (FIB-SEM) can also be deposited in EMPIAR.

The data is stored along with information (metadata) about the biological samples and the equipment used. EMPIAR curators manually annotate the data to a high standard using the web-based EMPIAR annotation system that displays the file information as it is extracted with such tools as IMOD and BSOFT.
