Protein secondary structure and environment assignment from atomic coordinates

SSEnvID is a program to recognize secondary structural elements in proteins from their atomic coordinates. It performs the same task as DSSP by Kabsch and Sander (1983) or STRIDE by Frishman & Argos (1995) with analyzing both hydrogen bond and mainchain dihedral angles, as well some probabilistic measures. SSEnvID also computes accessible surface area, polarity and environment classes as defined by Bowie, Luthy, Eisenberg (1991). SSEnvID's new feature is the probability (quality) of secondary structure assignment for each amino acids.
