iCn3D 2.18.0 is now available on NCBI web servers and from GitHub ( https://github.com/ncbi/icn3d ). Users can view SNPs of the 2019-nCov structures in the "Sequences & Annotations" window. Users can also access the 2D Interaction Network and 2D Interaction Map for protein-ligand or protein-protein interaction by selecting the menu "View > H-Bonds & Interactions". Another new feature is "icn3dpy", a Jupyter Notebook widget of iCn3D, which enables data scientists to use iCn3D in a Jupyter environment. Users can view a predefined display or create a custom view directly in the Jupyter Notebook. As an example the SNPs of the 2019-nCov spike (S) glycoprotein were viewed using a Jupyter Notebook and saved here as HTML.
