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

In Ubuntu spaced is provided by spaced package.

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.

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

sudo apt-get -y install spaced

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

You can also use apt command to install spaced.

sudo apt -y install spaced

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

sudo aptitude install spaced
