Most Next Generation Sequencing (NGS) analysis is done via the command line with typed text commands rather than using Graphical User Interfaces (GUIs) that are more common in day to day computer use. Additionally, rather than analysis being confined to your personal computer/laptop it is often beneficial to access shared computer resources such as those at TACC. This is done via Secure Shell (SSH) programs. Windows10 began including an "OpenSSH Client" package first as an optional feature before enabling by default. Installation of this feature enables access to some key commands on the windows command line, or power shell application. If you are already experienced with logging into remote computers on the command line via other programs, it is recommended that you continue to us those programs, but please note support may be more limited.
Tutorial Objectives:
- Ensure "OpenSSH Client" is activated on your computer
- Launch powershell command line interface.
- Use ssh command to log into lonestar5 on TACC.

As alluded to above, it is a relatively recent change by Microsoft/windows to recognize the usefulness of having an ssh client built into the operating system. As such historically there are , multiple alternatives that exist for ssh clients. While the commands in this class will be centered around the powershell environment with OpenSSH enabled, in your future work you may decide to branch out into alternatives. If you are already familiar with an alternative program, you are encouraged to continue using it.
At the end of the class several alternatives will be listed here with links for your future consideration.
