called ICEDUST (Integrated COMET Experiment Data User Software Toolkit), which
provides the ability to simulate, reconstruct and analyze data. The ability to
reconstruct and analyze data, treating simulated and real data in the same way,
is an essential feature that will allow COMET to achieve its sensitivity.
ICEDUST uses accurate descriptions of the experiment geometry and magnetic
field maps from the manufacturer of the superconducting magnets. The framework
also calibrates the data (through the use of constants stored in a database)
and distributes the data and processing using the Grid. Implementation of
COMET Phase-I in ICEDUST is currently underway.
\section{Summary}
The COMET (J-PARC E21) experiment is going to push the limit of experimental
