So,  I  finally  got  a  chance   to  play  around  with  it  this
evening. I  think I'm  pretty  close...but  I'm obviously  missing
something. Attached are both the .txt  output from spotread and my
attempt at  turning it  into a  .sp file. When I  try to  create a
profile with it, I get:

    profile: Error - Input file doesn't contain field SPEC_357

Sure  enough, it  doesn't  contain any  such  field. In fact,  the
string, ``357,'' is nowhere to be found in the file...which has me
quite puzzled.

So...what'm I missing?

Thanks,
