Electron Microscopy Electronic Notebook(EMEN)
EMEN (Electron Microscopy Electronic Notebook) is an object-oriented database used to record information about all aspects of transmission electron microscopy experiments, from specimen purification through final 3D reconstruction. EMEN is built on top of the object-oriented database and web-based application server, ZOPE. Several of the applications produced at the NCMI now interface with this database to deposit and retrieve data and metadata when necessary. After a year of use, EMEN serves approximately 5 TB of data contained in 2.1 million records.
