This is a collection of all the analysis tools that are part of *MedeA*.

The *MedeA’s* Geometry Analysis module performs interactive analysis of any crystalline
or non-crystalline periodic model, providing a wealth of information including detailed
symmetry analysis, atom coordinate and interatomic distance analysis, together with
pair correlation functions and powder diffraction patterns.

*MedeA’s* Void Finder lets you analyze interstitial space and directly insert atoms at high symmetry points inside the chemical unit cell.
It uses a Voronoi triangulation algorithm and displays candidate lattice points in a spreadsheet for analysis and processing.

*MedeA’s* Void Finder features include:

- Accounts for lattice symmetry and atomic radii
- Displays interstitial sites and local coordination
- Customizable upper/lower void-radius search limits
- Sortable table output
- One-click atom insertion and recalculation

*MedeA’s* Trajectories are created during geometry optimizations and molecular dynamics simulations,
monitoring the structures, energy contributions, forces and stress tensors as a function of the
simulation steps. *MedeA’s* Trajectories can be used in forcefield optimization processes.
*MedeA* offers visualization and animation of the structural evolution and a graph of the energy contributions.

Optical Spectra are calculated by molecular or solid state ab initio codes in *MedeA*.
For systems with periodic boundary conditions, frequency dependent optical functions are tensorial quantities.
The *MedeA Optical Spectra* tool visualizes all components of the dielectric function, conductivity,
refractive index, absorption index and reflectivity, and in a customized manner all combinations thereof.
For molecular systems *MedeA’s UV / Vis Spectra* displays stick spectra and broadened spectra,
including the intensities as calculated from the optical matrix elements and oscillator strengths.
The predicted spectra can be overlaid by experimental data, with customized scaling of
frequencies, intensities, and line widths.

Analysis of *MedeA’s* Molecular Orbitals permits to qualitatively predict,
describe, and understand the nature of the chemical bonds in molecules, complexes,
and weakly bound clusters, the reactivity of compounds and catalysts, and the
geometry of chemical species, among others.

*MedeA’s* Volume Rendering offers versatile and easy to use graphical tools that allow you
to visualize 3D computational data, such as total, valence, pseudo, and deformation charge densities,
magnetization densities, total local potentials, electron localization functions, molecular orbitals,
and Fermi surfaces.
The data can be visualized as isosurfaces overlaid with the atomic structure,
as color coded contour plots inside planes sliced
through the 3D data set, or as planar averages along specific directions in space.

This interactive tool is used to analyze UNCLE Monte Carlo temperature profiles and to study the temperature evolution of a model. Such a study allows one to identify phase transition temperatures. Furthermore, opening Monte Carlo snapshots containing thousands of atoms from a temperature profile facilitates the study of temperature dependent structural changes within the model.

*MedeA’s* UNCLE Monte Carlo Temperature Profile tool is part of *MedeA UNCLE*.

Fetch the ground state diagram from a binary UNCLE cluster expansion to identify
stable phases and interactively view these within *MedeA*.

*MedeA’s* Vibrational Property Analysis tool consists of visualization tools for phonon dispersions and
phonon densities of states for systems with periodic boundary conditions, as well as
Infrared and Raman spectra for both molecular as well as solid state and surface systems.
The phonon dispersion plots the frequencies of acoustic and optical phonon modes along a path
through the Brillouin zone. Each of these modes can be animated, i.e. a structural model is created
and the constituent atoms vibrate in directions and with amplitudes defined by the polarization functions.
The phonon density of states displays the number of modes encountered in a certain frequency interval,
with separate contributions of specific atoms and for different cartesian directions (x, y, z).
From the phonon density of states accurate temperature dependent thermodynamic functions are derived.
Infrared and Raman spectra including the intensities are displayed as stick spectra and broadened spectra.
For molecular systems, each of the modes can be animated from the corresponding stick representation.
The predicted spectra can be overlaid by experimental data, with customized scaling of
frequencies, intensities, and line widths.

*MedeA’s* Electronic Structure Analysis consists of visualization tools for band structures and densities of states.
A band structure plots energy bands along a path through the Brillouin zone and allows, for instance,
detailed analysis of band edge states in semiconductors and insulators.
The density of states displays the number of states encountered in a certain energy interval, with separate
contributions of specific atoms and for different angular momenta (s, p, d, f). These details
of the density of states enables an in-depth analysis of the electronic structure and bonding.

semiconductors, and insulators in **k**-space and lists the effective masses of all
bands at arbitrary **k**-points.

*MedeA’s* Electronic Transport provides the electronic contributions to the electric and
thermal conductivity, the thermoelectric power, and related functions as based on
semiclassical Boltzmann theory.

*MedeA Docking* automatically creates, adjusts, and refines host-guest and
surface-guest systems. The resulting host-guest structures can be employed in
forcefield and first-principles based simulations.

The *MedeA Morphology* module employs the lattice parameters, space group, and surface
stabilities of a given system to determine the possible terminating faces and morphology
of that crystal. These data determine the possible crystal faces and their relative
orientations. The overall shape of the crystal is determined by the relative importance
of each crystal face.
