[http://molviz.org/pacupp PACUPP]], '''P'''ockets '''A'''nd '''C'''avities '''U'''sing '''P'''seudoatoms in '''P'''roteins, identifies cavities by filling them with pseudoatoms (holmium, Ho, think "holes"; see comparison note<ref name="hitormiss" />). Cavities are identified as spaces between macromolecule atoms large enough to accomodate a ''cavity probe'' (default cavity probe radius 1.5 Å, configurable), or pockets between a smoothed macromolecular surface (default surface probe radius 10 Å, configurable) and atoms of the macromolecule. Starting point(s) are not relevant. An example is presented in some detail at [[PACUPP: Pockets And Cavities Using Pseudoatoms in Proteins]]. Further examples with demonstrations of how to use PACUPP are in a YouTube video and a slideshow, available from [http://molviz.org/pacupp molviz.org/pacupp], where you can also download the program.
