Detect 'pockets' in a protein structure using the fpocket software. A potential use 
of this tool is locating potential binding sites in a protein prior to performing 
protein-ligand docking.

To use, upload a protein structure in PDB format and select the type of pocket to 
detect. 'Custom options' can also be selected - this exposes all internal fpocket 
parameters. Using this option requires some knowledge of the fpocket prediction 
algorithm. Please consult the cited publications for more details.


-----

.. class:: infomark

**Input**

A protein structure in PDB format.

-----

.. class:: infomark

**Output**

Some or all of the following files:

- A collection of PDB files, one for each pocket, each containing the atoms bordering the pocket.
- A collection of PQR files, one for each pocket, each containing Voronoi vertices of the pocket.
- A single PQR file containing all Voronoi vertices for all pockets.
- A text file listing properties of all pockets detected.
