How To Install spaced on Kali Linux

Introduction

In this tutorial we learn how to install spaced on Kali Linux.

What is spaced

spaced is:

Spaced (Words) is a new approach to alignment-free sequence comparison. While most alignment-free algorithms compare the word-composition of sequences, spaced uses a pattern of care and don’t care positions. The occurrence of a spaced word in a sequence is then defined by the characters at the match positions only, while the characters at the don’t care positions are ignored. Instead of comparing the frequencies of contiguous words in the input sequences, this new approach compares the frequencies of the spaced words according to the pre-defined pattern. An information-theoretic distance measure is then used to define pairwise distances on the set of input sequences based on their spaced-word frequencies. Systematic test runs on real and simulated sequence sets have shown that, for phylogeny reconstruction, this multiple-spaced-words approach is far superior to the classical alignment-free approach based on contiguous word frequencies.

There are three methods to install spaced on Kali Linux. We can use apt-get, apt and aptitude. In the following sections we will describe each method. You can choose one of them.

Install spaced Using apt-get

Update apt database with apt-get using the following command.

sudo apt-get update

After updating apt database, We can install spaced using apt-get by running the following command:

sudo apt-get -y install spaced

Install spaced Using apt

Update apt database with apt using the following command.

sudo apt update

After updating apt database, We can install spaced using apt by running the following command:

sudo apt -y install spaced

Install spaced Using aptitude

If you want to follow this method, you might need to install aptitude on Kali Linux first since aptitude is usually not installed by default on Kali Linux. Update apt database with aptitude using the following command.

sudo aptitude update

After updating apt database, We can install spaced using aptitude by running the following command:

sudo aptitude -y install spaced

How To Uninstall spaced on Kali Linux

To uninstall only the spaced package we can use the following command:

sudo apt-get remove spaced

Uninstall spaced And Its Dependencies

To uninstall spaced and its dependencies that are no longer needed by Kali Linux, we can use the command below:

sudo apt-get -y autoremove spaced

Remove spaced Configurations and Data

To remove spaced configuration and data from Kali Linux we can use the following command:

sudo apt-get -y purge spaced

Remove spaced configuration, data, and all of its dependencies

We can use the following command to remove spaced configurations, data and all of its dependencies, we can use the following command:

sudo apt-get -y autoremove --purge spaced

Dependencies

spaced have the following dependencies:

• libc6
• libgcc-s1
• libgomp1
• libstdc++6
