rosetta.core.pose.PDBPoseMap:
PDBPoseMap can be queried with PDB information (chain, sequence
position) and returns a pose's resid position.
rosetta.core.pose.Pose:
The Pose class represents a molecular system (protein-dna-ligand...)
as a container of Rosetta Residue objects together with
a Conformation object that defines how internal coordinate changes
propagate through the system and an Energies object that stores
information from the last energy evaluation.
rosetta.core.pose.ResidueIndexDescription:
a class which can represent one of many ways in which to describe a
particular residue in a pose, and can, when given a pose, find its
index.
rosetta.core.pose.ResidueIndexDescriptionFromFile:
%ResidueIndexDescriptionFromFile differs from its parent only in
its error reporting when a residue index resolution fails: it
prints the file name and the line number that the residue index
data came from.
