hi, I just spent a bit of time trying to update my rusty knowledge of the reported forcefield terms. I thought I would post the list and see if people can improve on it. I tend to view this as very important info for non-guru users
fa_atr = full atom attraction
fa_rep = full atom repulsion
fa_sol = full atom solvation via Lazaridis-Karplus solvation model
fa_pair = full atom statistics based pair term, favors salt bridges
hbond_sr_bb = hydrogen short range backbone-backbone
hbond_lr_bb = hydrogen short range backbone-backbone
hbond_bb_sc = hydrogen bond backbone to sidechain
hbond_sc = hydrogen bond sidechain-sidechain
dslf_ss_dst = disulfide sulfur-sulfur distance?
dslf_cs_ang = disulfide carbon-sulfur angle?
dslf_ss_dih = disulfide sulfur-sulfur dihedral?
dslf_ca_dih = disulfide alpha carbon related? dihedral
rama = ramachandran statistical potential to disfavor rare regions
probability of phi/psi given amino acid
fa_dun = full atom Dunbrack rotamer statistics potential
p_aa_pp = probability of amino acid given phi and psi
ref = res type dependent reference energy for desolvation on folding
pro_close = pro_close is a term that ensures proline's ring stays closed
omega = statistical potential related to omega angle?
fa_intra_rep = full atom intra (ligand? rotamer?) repulsion (??)
