Where does the data come from?
EMPIAR stores and provides access to data from microscopy experiments performed in laboratories around the world. In addition to EMDB-related raw image data, EMPIAR will accept:
- 2D/3D data from 3D imaging modalities not covered by EMDB (e.g. 3D Scanning Electron Microscopy and Soft X-ray Tomography)
- 2D EM data used in integrative/hybrid methods, associated with a structure deposited in the PDB or PDB-Dev archive
- Certain reference and benchmark datasets (to be decided on a case-by-case basis)*
- Datasets used for certain community challenges (such as the 2015 Map Validation Challenge*)
*We are keen to support community challenges and archival of reference data sets. Please contact the staff of the EMPIAR archive prior to deposition.
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, BSOFT and EMAN2.
