Sure:

   larch> dat = read_ascii(datafile_name)
   larch> # ... make sure you have mu(E) as  'dat.energy' and 'dat.mu'

   larch> autobk(dat, rbkg=1.0, kweight=1)  # may want other options

   larch> write_ascii('my_chie.txt', dat.energy, dat.chie)
   larch> plot(dat.energy, dat.chie, xlabel='E (eV)', ylabel=r'$\chi(E)$')

Hope that helps,
--Matt
