The INRA-Minnesota Porcine Radiation Hybrid (IMpRH) Sewer provides both a m
apping tool (IMpRH mapping tool) and a database (IMpRH database) of officia
lly submitted results. The mapping tool permits the mapping of a new marker
relatively to markers previously mapped on the IMpRH panel. The IMpRH data
base is the official database for submission of new results and queries. Th
e database not only permits the sharing of public data but also semi-privat
e and private data.
