SecStAnT

SecStAnT is a tool for the automatic creation of data-sets of structures from Protein Data Bank (PDB) with user-defined structural composition, and for the calculation of their internal variables distributions.

SecStAnT is able to
1. Select from PDB data sets of structures based on user specified secondary structures (defined based on internal PDB classification or on DSSP) and/or sequence motives.
2. Build Data-sets at different levels of resolution (all atoms, only backbone, only Cα, ...)
3. Evaluate statistical distributions of internal variables:
a. single variable distributions (including the most relevant in the atomistic representation, e.g. PHI and PSI and a number of those for the Cα based representation)
b. two variables correlations (including the PHI-PSI Ramachandran map and its equivalent in the Cα based representation)
c. three variables correlations
