Prerequisites for CCT installation

• ImageMagick 6 or newer (*Note: only required for the build_blast_atlas_all_vs_all.sh command)

Instructions for obtaining and installing these prerequisites and CCT are given below for Mac OS X and Linux. The instructions will likely need to be adjusted depending on the particular OS you are using, and as new versions of the perquisites are released. To use CCT on a Windows system we recommend using the CCT virtual machine (see the 'CCT virtual machine' section below). The virtual machine can also be used on Mac OS X and Linux systems. The advantage of using the virtual machine is that all the dependencies are already installed.

Installation on Mac OS X

Install Xcode

Use Finder or Spotlight to determine whether the Xcode application is already installed on your system. If Xcode has not been installed and you are using Mac OS X Snow Leopard, install Xcode from the Mac OS X install DVD (insert the DVD and choose Optional Installs and run the Xcode installer). If Xcode has not been installed and you are using MacOS X Lion or newer, install Xcode through the Mac App Store (open the Mac App Store, search for Xcode, and install the application). If you are installing Xcode version 4.1 or newer, ensure that the command-line tools are installed by doing the following: after Xcode installation is complete, search for Xcode using the Finder or Spotlight and click on the Xcode icon to launch Xcode. Choose Xcode->Preferences .. from the menu bar, click on the Downloads icon to open the Downloads preferences panel. Within this panel click the Components tab and select the Command Line Tools option and install it using the Check and Install Now button. For MacOS X Mavericks and later, the Downloads pane of Xcode Preferences does not support downloading command-line tools; therefore follow the instructions provided on this technical note page on Apple's website.

For more information about Xcode including download links and frequently asked questions visit the support page on Apple's website.

The following CCT installation steps have been tested for Mac OS X 10.6.8 (Snow Leopard) with Xcode 3.2.6, for Mac OS X 10.7.3 (Lion) with Xcode 4.1 and for Mac OS X 10.11.6 (El Capitan) with Xcode 8.2.1.

CCT virtual machine

An alternative to downloading and installing the CCT prerequisites is to use a CCT virtual machine consisting of a Linux operating system with all the dependencies preinstalled. The CCT virtual machine runs in VirtualBox, which is freely available for Windows, Linux, Macintosh, and Solaris hosts.

Depending on the virtualization product used to run the machine you may be able to drag and drop files from your host OS to the virtual machine. If this feature does not work you can easily transfer files using a USB drive.

The CCT virtual machine has the following user account:

Numerous programs are included with this machine, including emacs and vim for viewing and editing text files, and xpdf for viewing pdf files.

Install VirtualBox Software

Before downloading the VirtualBox virtual machine, install the VirtualBox software on your computer. VirtualBox is available from http://www.virtualbox.org. You may also need to install the 'VirtualBox Extension Pack'.

Download the CCT virtual machine:

Download the virtual machine from here.

Run the virtual machine:

1. Launch VirtualBox and choose Import Appliance from the File menu.

2. In the Appliance Import Wizard that opens use the Choose button to select the ubuntu-bioVM.ova file that was downloaded.

3. Click Continue to view the virtual machine settings and click Done/Import to begin importing the virtual machine. This step may take a while to complete depending on your host.

4. Select the newly imported virtual machine in the VM VirtualBox Manager and click Start.

5. Log in to the virtual machine as user 'ubuntu' using the password 'pw2016#'.

Update CCT and test your setup:

1. Open the Terminal application by clicking on the Terminal icon, or by choosing Applications->Accessories->Terminal.

2. Download and extract the latest version of CCT, and prepare the COG files used for COG assignment by entering the following in the terminal from the home directory:

3. Navigate to the cgview_comparison_tool directory and run the test.sh script:

If the script is working you should see various progress messages as the maps are generated. To stop the test script, press Control-C.

Network troubleshooting

In case the scripts above in the Update CCT and test your setup section can't be executed, a network issue may be the cause. Please, try to solve these issues using the steps below.

1. Verify that your host OS has access to the internet and can access using a web browser or ping some internet addresses like the following:

   • www.google.com
   • www.amazon.com

2. Do the same now inside the virtual machine.

3. If some of the the addresses above cannot respond, check your firewall settings to see if your firewall is blocking in some way your access to sites located outside of your institution. You may need to talk to your Network Administrator.

4. In the VirtualBox Manager, select the virtual machine and click on the Settings icon in the toolbar. In the pop-up window that appears select Network. Verify that 'Enable Network Adapter' option is checked and 'Attached to:' combobox is set to NAT.

5. If problems persist, virtualbox.org forums provide specific answers for network problems for a variety of host operating systems, including Windows, Linux and Mac OS X. In addition, there is a Troubleshooting section in the VirtualBox manual.

6. You can also contact us by email. Please include your host OS information and the results you have obtained using the steps above.
