Currently in use at. Open Standards for Interactive Computing The Jupyter Notebook is based on a set of open standards for interactive computing. These open standards can be leveraged by third party developers to build customized applications with embedded interactive computing.Since I first heard about the Jupyter notebook around that time it was called ipython notebook I instantly adopted it into my work flow for rapid testing, developing and most of all experimenting and playing around with Python code.

I realized quickly how comfortable it is as a working environment and started creating notebooks using more and more of the capabilities. I began integrating plots, images, markdown notes and even creating slide presentation in jupyter. Mostly because it's written in Python and has a great assortment of methods for running and analyzing DFT calculations. It also provides a set of convenient methods for handling chemical structures including periodic ones.

The package comes with it's on GUI, that does a decent job when it comes to displaying and handling structures however when working in a notebook it would be great to have a tool that allows embedding the viewer inside the notebook.

Some time ago there was even a thread on the ase-users mailing list where a question about embedding ASE structures in a Jupyter notebook was raised. I found a few ways that enable the interactive visualization of chemical structures given as the Atoms objects internal representation in ASE in the notebook, that I think are interesting to try out:.

The list above is by no means complete and there are probably some other great tools that provide similar functionality, so if you think I skipped some important alternative - let me know.

Jupyter Notebooks to Interactive Dashboards with Python Voila Example..!!

ASE has a builtin format converter or writer to html that uses the x3dom library to create an interactive view of the molecular structure once you open or embed the generated html in a browser. You can interact with your molecule by rotating, translating zooming and panning the view. A small hurdle is that we would like to have the html as a string that can be passed to the HTML functions but the ASE html writer needs to write a physical file.

One of the ways of fixing this behavior is a to use a named temporary file from the tempfile package and a custom function that takes the Atoms objects and returns the html string.

If everything went well you should see a view widget with a trans-butene molecule displayed, similar to the one below. If you want to try it yourself on a couple more examples see, the short notebook I used to test this code.

The most feature rich option is offered by the nglview package that provides a Jupyter widget for interactive visualizations of chemical structures and trajectories. It is built on top of the NGL Viewer and it supports some of the more popular formats through a number of convenience functions.

The supported formats include:. Most importantly it also supports ase. Atoms though nglview. The feature that I really like, that is not available in other viewers, is displaying trajectories and sequences of structures, which makes it possible to visualize molecular vibrations, structure relaxation steps or reaction paths.

As an example consider viewing a vibrational mode from the trajectory file:. Moreover nglview let you save the movie as gif file.

If you need more control for tweaking the display you can activate the gui mode by passing an additional parameter to the viewer.

The embedding capabilities are nicely illustrated on the page provided by the author and the compatibility with Jupyter is demonstrated in this example notebook. The imolecule package can handle multiple file formats, and can take string representation of structures as well a read files, however it cannot handle the default ASE format.

It uses it's own molecule representation internally that is based on json so we can write a small function for converting ase.If you do most of your work in Jupyter notebooks, it can be convenient to have a quick visualisation tool to view the results of your latest computation from within the notebook, without having to flick between the notebook and your favourite molecule viewer.

It is based on the NGL vieweran embeddable webapp for macromolecular visualisation.

The nglvew module documentation can be found hereand in addition to handling the usual formats for molecular structure. I have been using nglview to look at the results from the fragment hotspot maps algorithm.

A key point of this visualisation is being able to control the threshold at which the maps are displayed: higher thresholds indicate stronger interactions. In the code snippet below, the hotspot results are housed in the folder. Bromodomains have an almost universally conserved asparagine residue that acts as key pharmacophoric feature.

The widget supports showing data from the file-system, online data bases and from objects of many popular analysis libraries including mdanalysis, mdtraj, pytraj, rdkit and more. Python packages are available from PyPI and bioconda. The integration with Jupyter is done through the ipywidgets package. Interactive computing is a crucial strategy to tackle any scientific data heavy problem.

It allows an exploratory process where each computation yields results that guide the next step, help verify previous steps and ultimately build knowledge. By providing inlined output visualizations and explanatory text, code and data are put into context. Performing analyses over large sets of molecular structures like the Protein Data Bank archive or trajectories from molecular dynamics simulations are challenging but common tasks in structural bioinformatics and computational biophysics.

Traditionally, standalone visualization packages like VMD Humphrey et al. However, while very powerful and rich via pluginsthose tools are rather monolithic. Integrating computation and visualization in Jupyter notebooks offers a more modular and easier to contribute to approach. Several Python libraries are available to do computations on molecular structures and trajectories, for example biopython Cock et al.

By integrating computations and interactive visualization, Jupyter notebooks enable exploratory analysis of molecular data. Here, we present NGLview, a widget that provides interactive molecular graphics within Jupyter notebooks. Related tools that integrate molecular graphics in Jupyter notebooks include 3dmol. The focus of NGLview is in offering a broad set of features via an API and the integration of many third-party libraries for computations on molecular data.

It allows interactive viewing of molecular structures as well as trajectories from molecular dynamics simulations Fig. Coordinates are sent frame by frame to the notebook allowing viewing of large trajectories. Example Jupyter notebook session. A topology and a trajectory are loaded with pytraj and then rendered with NGLview, showing a cartoon representation for the protein and a ball and stick representation for everything else.

An instance of the widget can either be constructed directly [ NGLWidget ] or via one of the convenience methods to quickly load data from another library [e. Each loaded object structure, trajectory, volume is displayed by any number of representations, for example cartoon or spacefill for molecular structures. Upon loading a set of default representations is displayed, but methods exist to add, change and remove representations.

The API contains many more methods to customize the visualization and interact with it. Moreover, structures can be downloaded from the Protein Data Bank or loaded from the file system. Although NGLview supports a large number of popular data sources library classes, online databases it is straightforward to add custom adaptors for structure or trajectory data.

Tutorials include setting up simulations, using Jupyter notebook remotely, basic visualization of molecules, visualize trajectories, including running simulations. Similar tasks can be performed with other analysis libraries e. HTMD, mdanalysis or mdtraj as well.
