Optional support for APBS Poisson-Boltzmann calculations within Tinker requires object libraries from the APBS 1.3 software package, but this is not included in the default Tinker build. Just follow the instructions in the /fftw/0README file.
While we do not provide the required FFTW libraries with the Tinker distribution, they are easy to build from the included FFTW source. The FFTW libraries must be available in the one of the locations searched by the Tinker Makefile prior to building Tinker executables. Tinker requires two object libraries from the FFTW Fourier transform package, libfftw3.a and libfftw3_threads.a. As noted below, the FFTW libraries must be available before building Tinker. Then issue the "make" command while in the /source directory. Small changes are needed near the top of the file to set directory names and activate the appropriate operating system and compiler.
To build using the Tinker Makefile, just copy /make/Makefile into the /source area of the distribution. Makefiles, a cmake configure script, as well as standalone scripts to compile, build object libraries, and link executables on a wide variety of machine-CPU-operating system combinations are provided. After unpacking the release, you can build a set of Tinker executables on almost any machine with a Fortran compiler.
Tinker is provided as a complete source distribution. We strongly suggest users switch to Tinker 8 with its many important new features and bug fixes. In particular, older versions of parameter files should not be used with Tinker 8 executables and vice versa. Please note that as with prior new releases, version 8 is neither backward nor forward compatible with earlier versions of Tinker. Other changes from the previous Tinker version include new and updated force field parameter sets and numerous minor additions and bug fixes, many of them suggested by users of the package. Additional big improvements include parallel neighbor list building and updating, and big reduction in iteration needed to converge AMOEBA polarization via an efficient PCG solver. Tinker 8 also implements improved OpenMP parallelization throughout additional parts of the code. Use of modules and greatly increased use of dynamic memory allocation means Tinker can now support very large molecular systems.
An important change in this new version is the switch from old-style common blocks to Fortran modules.
#Tinkertool brew update#
Tinker 8 is a major update of the Ponder Lab tool set for molecular mechanics and dynamics calculations.

The Tinker software contains a variety of interesting algorithms such as: flexible implementation of atomic multipole-based electrostatics with explicit dipole polarizability, various continuum solvation treatments including several generalized Born (GB/SA) models, generalized Kirkwood implicit solvation for AMOEBA, an interface to APBS for Poisson-Boltzmann calculations, efficient truncated Newton (TNCG) local optimization, surface areas and volumes with derivatives, free energy calculations via the Bennett Acceptance Ratio (BAR) method, normal mode vibrational analysis, minimization in Cartesian, torsional or rigid body space, symplectic RESPA multiple time step integration for molecular dynamics, velocity Verlet stochastic dynamics, pairwise neighbor lists and splined spherical energy cutoff methods, particle mesh Ewald (PME) summation for partial charges and polarizable multipoles, a novel reaction field treatment of long range electrostatics, fast distance geometry metrization with better sampling than standard methods, Elber's reaction path algorithm, potential smoothing and search (PSS) methods for global optimization, Monte Carlo Minimization (MCM) for efficient potential surface scanning, tools for fitting charge, multipole and polarization models to QM-based electrostatic potentials and more. Parameter sets for other widely-used force fields are under consideration for future releases. Tinker has the ability to use any of several common parameter sets, such as Amber (ff94, ff96, ff98, ff99, ff99SB), CHARMM (19, 22, 22/CMAP), Allinger MM (MM2-1991 and MM3-2000), OPLS (OPLS-UA, OPLS-AA), Merck Molecular Force Field (MMFF), Liam Dang's polarizable model, and the AMOEBA, AMOEBA+ and HIPPO polarizable atomic multipole force fields. The Tinker molecular modeling software is a complete and general package for molecular mechanics and dynamics, with some special features for biopolymers.
