Since July 1995, the European Bioinformatics Institute (EBI) has maintained
RHdb (http://www,ebi.ac.uk/RHdb), a public database for radiation hybrid d
ata. Radiation hybrid mapping is an important technique for determining hig
h resolution maps. RHdb is also served by CORBA servers. The EBI is an Outs
tation of the European Molecular Biology Laboratory (EMBL).
