GROMACS

Compare

  Analyzed about 21 hours ago

GROMACS is a versatile package to perform molecular dynamics, i.e. simulate the Newtonian equations of motion for systems with hundreds to millions of particles. It is primarily designed for biochemical molecules like proteins, lipids and nucleic acids that have a lot of complicated bonded ... [More] interactions, but but thanks to its speed, many groups also use it for research on non-biological systems, e.g. polymers. Speed is one of the key features that makes GROMACS particularly attractive. Thanks to the strong emphasis on bottom-up performance tuning: hand-tuned CPU SIMD kernels are available for most CPU architectures, CUDA-and OpenCL-based GPU acceleration together with efficient multi-threading and neutral-territory domain-decomposition with MPI SPMD parallelization is supported.

MDAnalysis is an object-oriented python toolkit to analyze molecular dynamics trajectories generated by CHARMM, NAMD, LAMMPS, or Gromacs. It allows one to read molecular dynamics trajectories and access the atomic coordinates through numpy arrays. This provides a flexible and relatively fast ... [More] framework for complex analysis tasks. In addition, CHARMM-style atom selection commands are implemented. Trajectories can also be manipulated (for instance, fit to a reference structure) and written out. Some time-critical routines are written in C or Cython and require a working C compiler. MDAnalysis comes with an expanding library of analysis functions such as RMSD-fitting or analysis of lipid membrane bilayers. [Less]

GromacsWrapper

Compare

  No analysis available

GromacsWrapper is a python package that wraps system calls to Gromacs tools into thin classes. This allows for fairly seamless integration of the gromacs tools into python scripts. This is generally superior to shell scripts because of python’s better error handling and superior data structures. It ... [More] also allows for modularization and code re-use. In addition, commands, warnings and errors are logged to a file so that there exists a complete history of what has been done. [Less]

gridcount

Compare

  Analyzed about 1 hour ago

gridcount is an analysis tool for Gromacs that creates 3D (number) densities from molecular dynamics trajectories. Typically, this is used to look at the density of water or ions near proteins or in channels. It provides tools to generate the 3D map in portable formats, 2D cylindrical averages and 1D linear averages ("density profiles")

g_count

Compare

  Analyzed about 2 hours ago

g_count and g_flux are simple Gromacs tools that are primarily useful to characterize movement of water inside a cylindrical region. This can be the pore of an ion channel or a carbon nanotube. g_count returns statistics about how many atoms of a certain type (for instance, water oxygens) occupied ... [More] the region of interest. g_flux calculates the flux through a cylindrical region. g_flux is more sophisticated than g_count and gives more detailed information. Citation: O. Beckstein and M. S.

Claimed by Max Planck Institute for Po... Analyzed about 11 hours ago

Charge carrier dynamics in an organic semiconductor can often be described in terms of charge hopping between localized states. The hopping rates depend on electronic coupling elements, reorganization energies, and driving forces, which vary as a function of position and orientation of the ... [More] molecules. The exact evaluation of these contributions in a molecular assembly is computationally prohibitive. Various, often semi-empirical, approximations are employed instead. The purpose of the toolkit is to simplify the workflow for charge transport simulations, provide a uniform error-control for the methods, flexible platform for their development, and eventually allow in silico pre-screening of organic semiconductors for specific applications.
