Solutions to travis: command not found

How To Fix travis: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu travis is provided by travis package.

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.

To fix this problem, we can install more using the command below.

sudo apt-get -y install travis

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install travis.

sudo apt -y install travis

Or if you have aptitude installed you can use the following command.

sudo aptitude install travis
