This course is the first one in our series of workshops on scientific computing, programming, data analysis and visualisation. It is intended for beginners with limited computer experience.
The course teaches the utilization of the bash shell, a command line interpreter for the UNIX or Linux operating system. Completing this course will enable you to use the institute's High Performance Computing cluster e.g. to run bioinformatic analysis pipelines or simulations that require lots of compute resources. The course will start with very simple commands to navigate the computer's file system. At the end, the participants will have learned how to write a script to execute complex tasks including launching parallel jobs on the cluster.
The course will be held on-site under "2G-hybrid" regulations (onsite participants must be vaccinated or have recovered from an infection, access via zoom is also possible). The number of participants is limited to 15.
Participants should have basic understanding of using a computer. At the course, we will provide PCs. Bringing your own laptop is ok, too.
Registration starts on Oct. 6. Follow this link to the registration form.
