ZClass is a Python object that takes input from a Protein Databank (PDB) file and converts it to a voxelised image. The voxelised image can then expressed in terms of an expansion in a basis set of Zernike polynomials which can be used to make rapid comparisons between different protein shapes.
Availability
ZClass is licensed under the GNU General Public Licence and can be freely downloaded and distributed. It is a Python class and needs to be accessed a part of a larger piece of Python code. There is currently no user-friendly interface, however if you're interested in working with us to develop one we would love to hear from you (maybe as a PyMol plugin). There is a PDF file associated with the library which gives instructions and examples on how to use the code. Download ZClass.
