From ALICE Documentation

This wiki is the main documentation source for information about the Academic Leiden Interdisciplinary Cluster Environment (ALICE) cluster. ALICE is the research computing facility of the partnership Leiden University and Leiden University Medical Center. It is available to any researcher from both partners. In this wiki, we will introduce the ALICE cluster in detail.

Below you find a collapsible tree structure of our documentation set which gives you a quick overview of the full navigation tree. The root tree items are also directory accessible from the top navigation bar.
