Software installation in a session

Different examples of installing scientific software in an Ubuntu session

Within a session, you have full control over the Ubuntu environment, including sudo privileges with the password ubuntu. This allows you to install software packages just as you would on any other Ubuntu system.

Example 1: Installing via command-line

You can install programs in a session using standard command-line tools such as sudo apt install or by extracting tarballs. In the following CloudPlay example, we install CCP4 following the official Linux installation instruction from the CCP4 website.

Example 2: Installation via a package manager

Some scientific software packages, like CCP4, provide a package manager that allows installation through a graphical user interface (GUI)

Step-by-step tutorial

  1. Download the CCP4 package manager for linux
  2. Follow the install instructions in the GUI

Example 3: Utilizing installation scripts

For commonly used scientific software, we provide installation scripts to streamline and simplify the installation process: dectris-cloud/scientific-software-installation

These scripts serve as an alternative to environments, making it possible to (1) provide installation instructions for non-distributable softwares that therefore cannot be shared via environments and (2) provide a streamlined and fast way of adding extra features to an existing session.

Step-by-step tutorial for installing CCP4 via provided installation script

  1. Download the installation script from the DECTRIS CLOUD script repository.
  2. Make the script executable via the command sudo chmod +x install_ccp4.sh.
  3. Execute the script via sudo ./install_ccp4.sh 
    1. In certain cases, you may be instructed to provide specific program or license files for the installation to proceed. If so, create the instructed install_files folder with mkdir install_files, and move the requested files there.
    2. Rerun sudo ./install_ccp4.sh to perform the installation with the installation files.
