CINDER Data – pyne.dbgen.cinder

This module locates, parses, and adds CINDER cross section and fission product yield data to nuc_data.h5. Note that this module requires that the cinder.dat file exist within the DATAPATH directory. This often requires that MCNPX is installed.

All functionality may be found in the cinder module:

from pyne.dbgen import cinder
