# WSx3DEM - The starting point. Function dsn returns a list of available Web Services (data sources).
# WSx3DEM_Reference - Reference server for 3D-EM volume map data from EMDB.
# WSx3DEM_Fitting - Alignment server based on hybrid models (PDB structures fitted into 3D-EM volumes).
# WSx3DEM_EMDB - Annotation server for 3D-EM volume maps.
WSx3DEM uses a client-server pattern to provide the structural 3D models maintained at the Electron Microscopy DataBase (EMDB) together with their related information (annotations).
