Detailed Description

Build loops from scratch.

Author: Kale Kundert; Roland A. Pache, PhD

Building a loop from scratch is useful in two scenarios. The first is when there's missing density that needs to be modeled, and the second is when the whole loop modeling algorithm needs to be benchmarked. This mover uses kinematic closure (KIC) to build loops. By default, the loop are built by picking phi and psi values from a Ramachandran distribution and setting all other DOFs to ideal values. Phi and psi values can also be picked using fragment libraries. Loop building succeeds when a model is found that passes a more-lenient-than-usual bump check. If no such model is found after 1000 iterations, the mover gives up and reports failure.

This process can be very slow for long loops, because there's nothing guiding the algorithm towards the right solution. By default, torsions are just being randomly picked, and they often won't fit in the relatively narrow space that's available. The problem is worse for interior loops than it is for surface loops, of course. This algorithm seems to work well enough on 12 residue loops, but beyond that it may be necessary to develop a smarter algorithm that preferentially builds into free space.
