Potentials are chosen with the use command. "use" is given a list of tokens which identify the potentials to use. The list is cleared with the token "none". For example, "use none bond angle; " resets the list and uses the bond and angle terms. "use hybrid;" just adds the hybrid terms to the list. "use angle bond none;" is equivalent to "use none;". You can manipulate the "use" command directly from the menu in winammp.

The potential types are given below, Bold are on by default.

bond	harmonic bond length
mmbond	MM3 bond function
hobond	homotopy bond (control with parameter lambda)
abc	angle-correlated bond length (requires abc data statement)
morse	Morse bond function (requires Morse data statement)
restrain	harmonic distance restraint (requires restrain data statement)
angle	harmonic angle
mmangle	MM3 angle function
cangle	UFF cosine angle function
hoangle	homotopy angle (control with parameter lambda)
torsion	torsion angle
hybrid	pyramid height
tether	harmonic position restraint
noel	split harmonic distance constraint
honoel	homotopy noel term (control with parameter lambda)
nonbon	point atom electrostatics and Van derWaals terms
screen	1s distributed charge electrostatics
debye	Debye screened potentials
shadow	4-D non-bonded for embedding.
none	reset the list
