General Information

Data Carpentry develops and teaches workshops on the fundamental data skills needed to conduct research. Its target audience is researchers who have little to no prior computational experience, and its lessons are domain specific, building on learners' existing knowledge to enable them to quickly apply skills learned to their own research. Participants will be encouraged to help one another and to apply what they have learned to their own research problems.

For more information on what we teach and why, please see our paper "Good Enough Practices for Scientific Computing".

Who: The workshop is aimed at graduate students and other researchers from the scientific community of Warsaw. The workshop is co-hosted by the University of Warsaw and the International Institute of Molecular Mechanisms and Machines (IMol) of the Polish Academy of Sciences. You don't need to have any previous knowledge of the tools that will be presented at the workshop.

Where: Room 2180, ul. Banacha 2, 02-097 Warszawa, Poland. Get directions with OpenStreetMap or Google Maps.

To participate in a Data Carpentry workshop, you will need access to software as described below. In addition, you will need an up-to-date web browser.

Please install a recent version of Python, preferably using the Anaconda installer, as well as a few required Python packages. The setup instructions for Anaconda installer and the required packages can be found at the overview site of the Data Analysis and Visualization in Python for Ecologists lesson. If you encounter any problems, you can get help during the troubleshooting session before the workshop.

We maintain a list of common issues that occur during installation as a reference for instructors that may be useful on the Configuration Problems and Solutions wiki page.
