Solutions to apbs: command not found

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

In Ubuntu apbs is provided by apbs package.

apbs is:

APBS is a software package for the numerical solution of the Poisson-Boltzmann equation (PBE), one of the most popular continuum models for describing electrostatic interactions between molecular solutes in salty, aqueous media. Continuum electrostatics plays an important role in several areas of biomolecular simulation, including:

  • simulation of diffusional processes to determine ligand-protein and protein-protein binding kinetics,
  • implicit solvent molecular dynamics of biomolecules ,
  • solvation and binding energy calculations to determine ligand-protein and protein-protein equilibrium binding constants and aid in rational drug design,
  • and biomolecular titration studies.

APBS was designed to efficiently evaluate electrostatic properties for such simulations for a wide range of length scales to enable the investigation of molecules with tens to millions of atoms.

This package contains the apbs program and utilities.

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

sudo apt-get -y install apbs

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

You can also use apt command to install apbs.

sudo apt -y install apbs

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

sudo aptitude install apbs
