This application in Rosetta3 was created and documented by David Johnson, et al.
This application takes in a PDB file and specified target residue/residue pair and, generates a (localized) PocketGrid, identifies the exemplar, and outputs it to a file. See the 2013 paper for PocketGrid algorithm details and the 2015 for exemplar creation algorithm details.

General Rosetta Options -database Path to rosetta databases -in:file:s Input pdb file(s) Pocket Identification Options -pocket_num_angles Number of different pose angles to measure pocket score at, default is 1, but at least 100 is recommended to reduce grid and orientation artifacts -pocket_grid_size Defines the dimensions of the PocketGrid centered on the target residue(s), or 10 Angstroms by default -pocket_psp Mark Pocket-Solvent-Pocket events as well, default=false -pocket_sps Unmark Solvent-Pocket-Solvent events, default=true -pocket_surface_dist Distance to consider pocket point being "surface" and excluded from "deep volume" -pocket_max_spacing Maximum residue-residue distance to be considered a pocket, default is 12 Angstroms -pocket_min_size Minimum pocket size to score, in cubic Angstroms, default is 10 cubic Angstroms -pocket_max_size Maximum pocket size to report, in cubic Angstroms, 0 for no limit (default) -pocket_probe_radius Radius of surface probe molecule, default 1.0 Angstroms -pocket_side Include only side chain residues for target surface, default=false -pocket_filter_by_exemplar Additional filter generates an exemplar and then restricts the pocket to that exemplars, defaul=false -pocket_limit_exemplar_color During clustering of exemplar atoms into exemplars, do not allow exposed color elements that are farther than 3 Angstroms apart to cluster together, creating a more concise exemplar, default=true -pocket_limit_small_exemplars Ignore exemplars with fewer than 5 hydrophobic atoms, default=true -pocket_ignore_buried Ignore pockets that are not solvent exposed, default=true -pocket_only_buried Identify only pockets buried in the protein core (automatically sets -pocket_ignored_buried false), default=false -pocket_static_grid By default the PocketGrid expands if pocket points are identified near the edge, this flag disables the autoexpanding feature. -pocket_grid_spacing Defines the spacing of the PocketGrid, 0.5 by default
