Does actual work for OptE minimization

Determine the metric for optimization of energy weights. Original source is Brian Kuhlman's FORTRAN weight training program. Since the goal is to maximize site-by-site sequence recovery, the metric is decomposable by positions, and this does the work for one position. First, a pass is made through all the rotamers at the position, and the lowest energy rotamer for each amino acid is identified. Next, a rough partition function is constructed. The score to be minimized is the negative log of the probabilty of selecting a native aa rotamer (needn't be the native conformation).

Limitations:

  1. Assumes that the choices available at each position are the 20 canonical amino acids - no DNA base recovery, no pTyr.
  2. Doesn't have Chris Saunder's compositional constraints. This would require implementation of a direction-set ( aka powell ) minimizer, as his optimization metric doesn't yield gradients.
