Dictionary of Algorithms and Data Structures (DADS)

Data provided by  National Institute of Standards and Technology

The Dictionary of Algorithms and Data Structures (DADS) is an online, publicly accessible dictionary of generally useful algorithms, data structures, algorithmic techniques, archetypal problems, and related definitions. In addition to brief definitions, some entries have links to related entries, links to implementations, and additional information. DADS is meant to be a resource for the practicing programmer, although students and researchers may find it a useful starting point.

Python Package for Generating LAMMPS Input Scripts for Alchemical Processes: generate_alchemical_lammps_inputs

Data provided by  National Institute of Standards and Technology

The parsers featured in this module are constructed to parse LAMMPS output files, (i.e., dump files), containing data for given potential energy values (an approximation of the Hamiltonian), U_{𝞴,𝞴'}, at specified values of 𝞴 and 𝞴', where varies from one to zero scaling the potential between solute and solvent in a reversible manner. The system is equilibrated at a 𝞴-state and energy values are evaluated at alternative 𝞴 values denotes by, 𝞴'. Because generating the input files can be cumbersome, functions have been included to generate the appropriate sections.

Polymer Builder Extension for MosDef-mBuild: mbuild_polybuild

Data provided by  National Institute of Standards and Technology

When modeling polymers in simulations, building a simulation box is a consistent barrier. Although many tools now exist for that purpose, not one contains all features that one would desire. A more specific failing is the handling of the polymer tacticity. MosDef's mBuild [DOI: 10.1007/978-981-10-1128-3_5] offers the flexibility to account for this important aspect of polymer structure, although not readily. This package contains mBuild "recipies" for common polymer backbone chemistries as well as common functional groups.

LAMMPS Simulation Data of Alchemical Processes

Data provided by  National Institute of Standards and Technology

This data includes a four alchemical processes with data files generated with the python package: generate_alchemical_lammps (DOI from MIDAS) and the resulting output to be used for the calculation of free energies using Multi-state Bennett Acceptance Ratio (MBAR), BAR, or Thermodynamic Integration (TI). These input files are only applicable for LAMMPS versions after April 2024. The four cases can be separated into two systems, benzene solvated in water, and a Lennard-Jones (LJ) dimer in solvent. These four cases are:
