ProDy is a free and open-source Python package for protein structure, dynamics, and sequence analysis. It allows for comparative analysis and modeling of protein structural dynamics and sequence co-evolution. Fast and flexible ProDy API is for interactive usage as well as application development. ProDy also comes with several analysis applications and a graphical user interface for visual analysis.

ProDy has a modular structure with modules inside various subpackages.
The main ones are:
:mod:~prody.atomic`` handles all :class:~prody.atomic.Atomicobjects including :class:~prody.atomic.AtomGroupand :class:.Selection`
:mod:~prody.database interfaces with databases such as CATH, DALI, UniProt and Pfam
:mod:~prody.dynamics provides all the modules for normal mode analysis with various elastic network models,
as well as PCA, SignDy (:mod:~prody.dynamics.signature), hybrid methods such as :mod:~prody.dynamics.clustenm,
allosteric signal propagation methods :mod:~prody.dynamics.perturb (PRS) and :func:~prody.dynamics.analysis.calcHitTime (Markovian hitting time),
and various analysis and plotting functions.
:mod:~prody.ensemble enables construction of heterogeneous structural ensembles for exploring dynamics from experiments and simulations
:mod:~prody.proteins provides various modules for parsing different kinds of protein structure files including PDB, mmCIF, MMTF and maps,
as well as tools to align and compare structures, and analysis of :mod:~prody.proteins.interactions within and between proteins (InSty) and
find :mod:~prody.proteins.waterbridges (WatFinder).
:mod:~prody.sequence has all the sequence alignment and evolutionary analysis tools of Evol
Smaller ones include:
:mod:~prody.chromatin specific to chromatin dynamics (ChromDy) including :mod:~prody.chromatin.hic and :mod:~prody.chromatin.cluster
:mod:~prody.compounds for parsing small molecule compounds/ligands from the PDB and related databases
:mod:~prody.domain_decomposition for Spectrus dynamical domain decomposition
:mod:~prody.trajectory for trajectories in DCD format
:mod:~prody.utilities

Hbp module: The calculation of hydrophobic interactions, solvent accessible surface area (SASA) and volume for each residue is using geometric methods based on the information of the atoms in the molecule. The methods have been programmed in C++ and can be compiled as a python module “hpb.so” which is then used by ProDy. Files for compilation are stored at prody/proteins/hpbmodule folder and required C++ and Fortran compiler. After compilation hpb.so file can be stored in prody/proteins folder in ProDy or in the local directory which is used to perform calulations. The precompiled versions for Python 2.7, 3.8, 3.9, and 3.10 are availabe in prody/proteins/hpbmodule. The user can choose the correct version of hpb.so and copy to the prody/proteins or local directory.
C++ code of hpb.so was developed by Xin Cao and Fortran code by Xin Cao, Michelle H. Hummel, Bihua Yu, and Evangelos A. Coutsias (License in prody/proteins/hpbmodule folder). Details of the method can be found in the Supplementary Material of InSty manuscript (soon will be submitted for publication).
