MAICoS

MAICoS stands for Molecular Analysis for Interfacial and Confined Systems. It is an object-oriented Python toolkit for analyzing the structure and dynamics of interfacial and confined fluids from molecular simulations. Combined with MDAnalysis, MAICoS enables the extraction of density profiles, dielectric constants, and transport properties from trajectory files generated by LAMMPS, GROMACS, CHARMM, or NAMD simulations. MAICoS is open source and released under the GNU General Public License v3.0.

MAICoS is designed both for beginners in molecular simulations with no prior Python experience— offering a descriptive Command Line Interface (CLI)—and for experienced users who can use the Python API for day-to-day analysis or build their own workflows for interfacial and confined systems.

Stay up to date with MAICoS news by following us on X. If you encounter any issues, report them on GitHub, or join our developer community on Discord to discuss features and improvements.

Basic Example

Here is a simple example showing how to use MAICoS to extract a density profile from a molecular dynamics simulation. The files conf.gro and traj.trr correspond to output files from a GROMACS simulation. In a Python environment, type:

import MDAnalysis as mda
import maicos

u = mda.Universe("conf.gro", "traj.trr")
dplan = maicos.DensityPlanar(u.atoms).run()

The density profile is stored in dplan.results.profile, and the corresponding bin positions are available in dplan.results.bin_pos.
