This tutorial explains how to use the BridgeDb identifier mapping service to translate HGNC names to Ensembl identifiers with Python (using a Jupyter Notebook). This step has been created as a part of the OpenRiskNet use case to link Adverse Outcome Pathways to WikiPathways. The original tutorial can be found here. Additionally, this tutorial can be interactively run through the Google Colab found here (you can also click the Google Colab badge at the top of this page).
