Introduction
In this tutorial we learn how to install crac on Kali Linux.
What is crac
crac is:
CRAC is a tool to analyze High Throughput Sequencing (HTS) data in
comparison to a reference genome. It is intended for transcriptomic
and genomic sequencing reads. More precisely, with transcriptomic
reads as input, it predicts point mutations, indels, splice junction,
and chimeric RNAs (ie, non colinear splice junctions). CRAC can also
output positions and nature of sequence error that it detects in the
reads. CRAC uses a genome index. This index must be computed before
running the read analysis. For this sake, use the command “crac-index”
on your genome files. You can then process the reads using the command
crac. See the man page of CRAC (help file) by typing “man crac”. CRAC
requires large amount of main memory on your computer. For processing
against the Human genome, say 50 million reads of 100 nucleotide each,
CRAC requires about 40 gigabytes of main memory. Check whether the
system of your computing server is equipped with sufficient amount of
memory before launching an analysis.
There are three methods to install crac 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 crac Using apt-get
Update apt database with apt-get using the following command.
sudo apt-get updateAfter updating apt database, We can install crac using apt-get by running the following command:
sudo apt-get -y install cracInstall crac Using apt
Update apt database with apt using the following command.
sudo apt update
After updating apt database, We can install crac using apt by running the following command:
sudo apt -y install cracInstall crac 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 updateAfter updating apt database, We can install crac using aptitude by running the following command:
sudo aptitude -y install crac
How To Uninstall crac on Kali Linux
To uninstall only the crac package we can use the following command:
sudo apt-get remove crac
Uninstall crac And Its Dependencies
To uninstall crac and its dependencies that are no longer needed by Kali Linux, we can use the command below:
sudo apt-get -y autoremove crac
Remove crac Configurations and Data
To remove crac configuration and data from Kali Linux we can use the following command:
sudo apt-get -y purge crac
Remove crac configuration, data, and all of its dependencies
We can use the following command to remove crac configurations, data and all of its dependencies, we can use the following command:
sudo apt-get -y autoremove --purge crac
Dependencies
crac have the following dependencies:
