Since July 1995, the European Bioinformatics Institute (EBI) has maintained
the Radiation Hybrid database (RHdb; http://www.ebi.ac.uk/RHdb), a public
database for radiation hybrid data. Radiation hybrid mapping is an importan
t technique for determining high resolution maps. Recently, CORBA access ha
s been added to RHdb. The EBI is an Outstation of the European Molecular Bi
ology Laboratory (EMBL).
