How To Install travis on Ubuntu 18.04
Introduction
In this tutorial we learn how to install travis on Ubuntu 18.04.
What is travis
travis is:
TRAVIS (Trajectory Analyzer and Visualizer) is a free tool for analyzing and visualizing trajectories from all kinds of Molecular Dynamics or Monte Carlo simulations. The aim of TRAVIS is to collect as many analyses as possible in one program, creating a powerful tool and making it unnecessary to use many different programs for evaluating simulations. This should greatly rationalize and simplify the workflow of analyzing trajectories. The following analysis functions are available:
Static (time independent) Functions:
- Radial, Angular, Dihedreal or Combined Distribution Function
- Point-Plane or Point-Line Distance Distribution
- Plane Projection Distribution
- Fixed Plane Density Profile
- Density, Spatial or Dipole Distribution Function
Dynamic (time dependent) Functions:
- Velocity Distribution Function
- Mean Square Displacement / Diffusion Coefficients
- Velocity Autocorrelation Functions
- Vector Reorientation Dynamics
- Van Hove Correlation Function
- Aggregation Functions (DACF, DLDF, DDisp)
Spectroscopic Functions:
- Calculate Power Spectrum
- Calculate IR Spectrum
- Calculate Raman Spectrum
TRAVIS can read trajectory files in XYZ, PDB, LAMMPS or DLPOLY format.
