PSS - Protein Structural Statistics


PSS is a protein structural statistics program for Unix-like environments. It is written in Perl, has a command-line interface, and is distributed under the GNU General Public License.

PSS reads an ensemble of PDB files of protein structures, performs a multiple sequence alignment, and computes structural statistics for each position of the alignment. Different optional functionalities are proposed: structure superposition, Cartesian coordinate statistics, dihedral angle calculation and statistics, and a cluster analysis based on dihedral angles. An HTML report containing a summary of results and figures can also be generated.
