mafft-homologs command not found

In this troubleshooting guide we learn how to fix mafft-homologs command not found error message

Introduction

When you run more command in linux terminal / console, you get the following error message

mafft-homologs: command not found

or when using sudo you get the following error message

sudo: mafft-homologs: command not found

In Ubuntu mafft-homologs is provided by mafft package.

mafft is:

MAFFT is a multiple sequence alignment program which offers three accuracy-oriented methods:

L-INS-i (probably most accurate; recommended for <200 sequences; iterative refinement method incorporating local pairwise alignment information),
G-INS-i (suitable for sequences of similar lengths; recommended for <200 sequences; iterative refinement method incorporating global pairwise alignment information),
E-INS-i (suitable for sequences containing large unalignable regions; recommended for <200 sequences), and five speed-oriented methods:
FFT-NS-i (iterative refinement method; two cycles only),
FFT-NS-i (iterative refinement method; max. 1000 iterations),
FFT-NS-2 (fast; progressive method),
FFT-NS-1 (very fast; recommended for >2000 sequences; progressive method with a rough guide tree),
NW-NS-PartTree-1 (recommended for ∼50,000 sequences; progressive method with the PartTree algorithm).

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

sudo apt-get -y install mafft

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

You can also use apt command to install mafft.

sudo apt -y install mafft

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

sudo aptitude install mafft
