There is a new version of MOLE check it out!

MOLE is an universal toolkit for rapid and fully automated location and characterization of channels, tunnels and pores in molecular structures. The core of MOLE algorithm is a Dijsktra path search algorithm, which is applied to a Voronoi mesh. MOLE is a powerful software (overcomming some limitations of Caver tool) for exploring large molecular channels, complex networks of channels and molecular dynamics trajectories (AMBER ascii traj and parm7 are supported) in which analysis of a large number of snapshots is required.

Program is available as standalone application for Linux(Unix), MacOS and Windows. Plugin for pyMol enables calling the MOLE program via an user friendly interface and allows results visualization. The on-line interface provides another interactive and easy-to-use interface to analyze molecular channels.

Tutorial is also available.
