virtual

Automatically generated virtual destructor for class deriving directly from ReferenceCount.

constructor

Note from rhiju & andrew leaver-day: we should get rid of command-line option calls here in favor of setting options from EtableOptions object. Would allow user to have multiple etables around!

calculate fast lookup arrays for vdw and solvation energy

Etable::make_pairenergy_table

Detailed:

Several energies are precomputed when fullatom mode is initialized and stored in lookup tables to speed fullatom calculation. Currently pre-computed values are the Lennard-Jones van der Waals approximation (lj) and the Lazaridis-Karplus implicit solvation function (lk). For each of these energies the derivative w.r.t. atom pair separation distance is calculated and stored as well. Note that the lj energy is artificially divided into atractive and repulsive components.

modify Etable to better treat 0-0, C-C, and H-H interactions

modify_pot

Detailed:: $$$ the Etables are modified in three ways: $$$ (1) the LK solvation energy is set to a constant below 4.2A to avoid shifting the position $$$ of the minimum on the LJatr potential. in refined decoys the peak in the C C pair $$$ distribution function shifts to around 3.8 A from ~4.0A in native structures; the LJatr $$$ potential has a minimum at 4.0A but this shifts towards smaller values because of the LK $$$ solvation term, which became increasingly favorable at shorter distances $$$ (2) the backbone carbonyl oxygen-carbonyl oxygen LJrep term has been modified to become $$$ moderately repulsive at distances less than 3.6A. this is to counteract the favorable $$$ LJatr between the atoms (which have radii of ~1.4A and so a minimum at ~2.8A; very few $$$ counts are observed in the pdb until around 3.2A) which leads to a significant shift in the $$$ O O pair distribution function towards smaller values in refined decoys. the repulsion is $$$ a temporary proxy for the lack of explicit electrostatic repulsion in the current force $$$ field. $$$ (3) a third soft repulsion between non polar hydrogens that was also based on comparison of $$$ refined decoy to native pdf's is currently commented out as the effects on packing have not $$$ been tested. it was observed that the protons tend to pile up at just beyond the point $$$ where the repulsion becomes strong, perhaps due to a general tendency to overcontraction $$$ because of long range LJatr interactions not compensated by interactions with solvent $$$ (which are of course missing)

Comments from DB: db the following function call modifies the potential in three ways: db (1) the solvation energy for nonpolar atoms is held constant below db 4.2A to avoid shifting the minimum in the LJ potential. db (2) a short range repulsion is added between backbone oxygens which are db otherwise brought too close together by the LJatr. db (3) the range of the repulsive interaction between non polar hydrogens is db increased slightly. (this is currently commented out because the effects db on design have not been tested)

Data needed to describe the splines for the fasol term: There are two cubic_polys needed: one to smooth the transition to where the fasol term goes flat as the distance becomes less than the sum of the van der Waals radii (the "close" cubic_poly), and a second to smooth the transition where the distance goes to the fa_max_dis and the energy goes to 0 (the far cubic_poly). In between the close and far values, the exponential form of the energy function is used.
