Tinker (software)

Tinker, previously stylized as TINKER, is a suite of computer software applications for molecular dynamics simulation. The codes provide a complete and general set of tools for molecular mechanics and molecular dynamics, with some special features for biomolecules. The core of the software is a modular set of callable routines which allow manipulating coordinates and evaluating potential energy and derivatives via straightforward means.

Tinker works on Windows, macOS, Linux and Unix. The source code is available free of charge to non-commercial users under a proprietary license. The code is written in portable FORTRAN 77, Fortran 95 or CUDA with common extensions, and some C.

Core developers are: (a
the Jay Ponder lab
at the Department of Chemistry, Washington University in St. Louis, St. Louis, Missouri. Laboratory head Ponder is Full Professor of Chemistry, and of Biochemistry & Molecular Biophysics; (b
the Pengyu Ren lab
at the Department of Biomedical Engineering University of Texas in Austin, Austin, Texas. Laboratory head Ren is Full Professor of Biomedical Engineering; (c
Jean-Philip Piquemal's research team
at Laboratoire de Chimie Théorique, Department of Chemistry, Sorbonne University, Paris, France. Research team head Piquemal is Full Professor of Theoretical Chemistry.

Features

The Tinker package is based on several related codes: (a
the canonical Tinker
version 8, (b) the Tinker9 package as a direct extension of canonical Tinker to GPU systems, (c
the Tinker-HP package
for massively parallel MPI applications on hybrid CPU and GPU-based systems, (d) Tinker-FFE for visualization of Tinker calculations via a Java-based graphical interface, and (e
the Tinker-OpenMM package
for Tinker's use with GPUs via an interface for the OpenMM software. All of the Tinker codes are available from the TinkerTools organization site on GitHub. Additional information is available from the TinkerTools community web site.

Programs are provided to perform many functions including:
# energy minimizing over Cartesian coordinates, torsional angles, or rigid bodies via conjugate gradient, variable metric or a truncated Newton method
# molecular, stochastic, and rigid body dynamics with periodic boundaries and control of temperature and pressure
# normal mode vibrational analysis
# distance geometry including an efficient random pairwise metrization
# building protein and nucleic acid structures from sequence
# simulated annealing with various cooling protocols
# analysis and breakdown of single point potential energies
# verification of analytical derivatives of standard and user defined potentials
# location of a transition state between two minima
# full energy surface search via a ''Conformation Scanning'' method
# free energy calculations via free energy perturbation or weighted histogram analysis
# fitting of intermolecular potential parameters to structural and thermodynamic data
# global optimizing via energy surface smoothing, including a ''Potential Smoothing and Search'' (PSS) method
