AMBER?

["Close, David M." <CLOSED at.at mail.etsu.edu>]

  I tried to do an AMBER calculation on guanine.  The Gaussian manual said
 GaussView would generate the coordinates for this calculation.  I tried this,
 but the calculation fails with 3 comments:
              stretching parameters undefined
 and 8 comments
 	bending parameters undefined
 and a final comment
 	not enough parameters to run AMBER.
   I do not have any information on AMBER other than the original 1995 JACS
 article.  Any hints on how to proceed?
