Installing Circos for use with HOMER can be divided into
3 parts. If you already use Circos on your system,
you may only need to pay attention to the last part.
I recommend checking out the official Circos installation
directions. Below is a quick guide with tips:
1. Download the Circos software and unzip it into a location where you won't delete it.
You want to download the general circos package (i.e. circos-0.62-1.tgz). Save it to location, and unzip it (tar zxvf circos-0.62-1.tgz). (At this point you can also do step 3, which is add the circos bin/ directory to you executable PATH.
2. Upgrade your Perl modules to include the necessary prerequisites for Circos.
Follow the instructions on this page: Perl and Modules. It talks a little while as some of the modules will want to install dependencies. For the most part, this means running the command:
By far the trickiest part is installing GD - often, you need to install the system C libraries for GD. This often means running something like:3. Add the Circos bin directory to you executable path so that you can run it by simply typing "circos" in the command line. (i.e. edit your ~/.bashrc or ~/.bash_profile file to include "PATH=$PATH:/Users/chucknorris/circos-0.54/bin/")
Try to follow the Circos instructions. Hopefully, buy the time you read this, it will be magically easier.
Linux (Ubuntu): "sudo apt-get install lib-gd2"
Linux (Redhat/CentOS): " yum install gd-devel"
Mac OSX: "sudo fink install gd2".
