GSoC Ideas 2018
Guidelines
Open Chemistry is an umbrella for projects in chemistry, materials science, biochemistry, and related areas. We intend to concentrate mainly on projects to improve Avogadro 2, cclib, 3DMol, and Open Babel. We have gathered a pool of interested mentors together who are seasoned developers in each of these projects. We welcome original ideas in addition to what's listed here - please suggest something interesting for open source chemistry!

Proposal Guidelines
Students need to write and submit a proposal, we have added the applying to GSoC page to help guide our students on what we would like to see in those proposals.
Avogadro 2 Project Ideas
Avogadro 2 is a chemical editor and visualization application, it is also a set of reusable software libraries written in C++ using principles of modularity for maximum reuse. We offer permissively licensed, open source, cross platform software components in the Avogadro 2 libraries, along with an end-user application with full source code, and binaries.
Project: Integrate with VTK: Volume Rendering and Charts
Brief explanation: Volume rendering is great for visualizing electronic structure, and VTK also brings charts for quantitative data
Expected results: The Visualization Toolkit (VTK) features a number of rendering techniques for 3D geometry (including volume rendering), and 2D charts (line, points, parallel coordinates, scatter plot matrices). These are all written using a recently updated OpenGL backend, and recent improvements to the Qt5 code in VTK make integration with Avogadro much simpler. This project would focus primarily on exposing the QVTKOpenGLWidget to Avogadro 2, and then exposing volume rendering for 3D electronic structure data, and tables in the charts. Integration would involve developing some interface classes that make it easy to interact with the VTK classes from Avogadro code, and some concrete implementations showing data in these widgets.
Prerequisites: Experience in C++, some experience with OpenGL ideal, but not necessary.
Mentor: Marcus D. Hanwell (marcus dot hanwell at kitware dot com).
Project: Biological Data Visualization
Brief explanation: Support for biological data, representations, and visualization
Expected results: Add support for molecular fragments on top of the molecule model, extending this to residues, and supporting reading/writing this secondary structure (e.g., PDB format). Additional rendering modes for secondary biological structures (i.e. ribbons, cartoons, etc.), building up a biomolecule from residues, and adding residue labels. Code and algorithms may be adapted from 3DMol.js. Since biological molecules are often large (10^3 to 10^6 atoms and bonds), such implementations should be highly efficient and optimized, adopting symmetry and other techniques to improve interactivity and rendering performance.
Prerequisites: Experience in C++, some experience with OpenGL and an biochemistry ideally, but not necessary.
Mentor: Marcus D. Hanwell (marcus dot hanwell at kitware dot com) or Geoffrey Hutchison (geoffh at pitt.edu)
Project: Molecular Dynamics
Brief explanation: Improve support for running, reading, and analyzing molecular dynamics simulations in Avogadro 2
Expected results: Code for running MD simulations in common packages (e.g., OpenMM, GROMACS, etc.) including extracting parameters and atom types from Open Babel. Initial support for reading in basic trajectories from XYZ files, and static .gro files for GROMACS already exists. Extend this to more fully support the needs of molecular dynamics, reading in trajectory files, ideally loading in time steps on demand for large files rather than loading the entire file in up front (as is currently the case). Investigate whether compression techniques (e.g., delta compression) can improve reading and rendering performance. Investigate ways to support generating input, and dealing with large systems (over one million particles). Add support for characterizing particle movement (e.g., pair-wise distribution functions), rare events, and visualizing these in addition to simple trajectory animations.
Prerequisites: Experience in C++, some experience with OpenGL and an MD code ideal, but not necessary.
Mentor: Marcus D. Hanwell (marcus dot hanwell at kitware dot com).
Project: Scripting Bindings
Brief explanation: Implement an embedded scripting language (e.g., Python or JavaScript) in Avogadro 2
Expected results: Create bindings for the C++ libraries in Python or JavaScript / QtScript. This should allow an embedded scripting console as well as support for implementing modular extensions (tools, rendering, etc.) in Python or JavaScript. A Boost.Python implementation existed in Avogadro v1, and some rudimentary support has been re-implemented using PyBind11 with the new code base. An ideal solution would connect to QML and Qt to allow scripting to add menu items, windows, etc. and provide documentation and example scripts. The interface should be maintainable as new classes and methods are added.
Prerequisites: Experience in C++ and Python or JavaScript, some experience with PyBind11, SWIG, Boost.Python, or similar packages (SIP, PySide, etc.) suggested.
Mentor: Geoff Hutchison (geoffh at pitt dot edu) or Marcus D. Hanwell (marcus dot hanwell at kitware dot com)
Project: Integrate with RDKit
Brief explanation: Integrate the RDKit toolkit into Avogadro for conformer sampling and force field optimization
Expected results: RDKit is a BSD-licensed cheminformatics toolkit with a wide range of features useful for Avogadro 2. Most notably, RDKit offers efficient and accurate 3D coordinate generation, conformer sampling, and force field optimization. Implement a connection between Avogadro objects (molecules and atoms) and RDKit objects and implement conformer sampling and force field optimization code.
'Prerequisites: Experience in C++, some experience with Python will be helpful.
Mentor: Geoff Hutchison (geoffh at pitt dot edu)
Open Babel Project Ideas
Open Babel is an open toolbox for chemistry, designed to speak the many languages of chemical data. It's an open, collaborative project allowing anyone to search, convert, analyze, or store data from molecular modeling, chemistry, solid-state materials, biochemistry, or related areas.
Project: Implement MMTF format
Brief explanation: Implementation of MMTF file format in OpenBabel.
Expected results:' Macromolecular Transmission Format (MMTF) is a new compact binary format to transmit and store biomolecular structural data quickly and accurately (http://mmtf.rcsb.org). Your task is to implement support for this format in the OpenBabel open-source cheminformatics toolkit (http://openbabel.org). Code will be written in C++.
Mentor: Geoff Hutchison (geoffh at pitt dot edu) or David Koes (dkoes at pitt dot edu)
Project: Fast, Efficient Fragment-Based Coordinate Generation
Brief explanation: A critical challenge is generating 3D coordinates for a known molecule. Implement a fragment-based generator to supplement the rule-based algorithm.
Expected results: Many representations in chemistry either store no coordinates (SMILES, InChI, FASTA sequence) or 2D coordinates. Performing calculations requires the full 3D reconstruction of a molecule, ideally with a low-energy conformation. Currently, Open Babel uses a combination of a rule-based approach (i.e., expected geometries) to generate atom-by-atom the 3D coordinates of molecules. Fragments are only used for some ring-based structures. For inorganic and organometallic molecules, the rules may fail.
Importantly, the approach is highly efficient, since fragments can set many atoms at once. The project should generate a library reflecting a balance between efficiency (i.e., many common fragments) and size, as well as an efficient, parallel algorithm for connecting fragments. A knowledge-based fragment approach can also supplement and minimize the need for conformer sampling.
A recent research paper describing one such approach can be found here
Prerequisites: Experience in C++ and linear algebra. Knowledge of statistics (e.g., Bayesian inference, data mining), OpenMP or OpenCL ideal.
Mentor: Geoff Hutchison (geoffh at pitt dot edu) or David Koes (dkoes at pitt dot edu)
Project: Bayesian Optimization of Conformer Geometries
Brief explanation: Most molecules have multiple energetically-accessible geometries (conformations). In even medium-sized molecules, there may be thousands or millions of possibilities. Intelligent search strategies (i.e., Bayesian optimization) are needed to find the best geometries in the shortest amount of time.
Expected results: An efficient implementation of Bayesian optimization of molecular dihedral angles and testing against known molecular geometries (crystal structures) and libraries of conformers. In principle, the goal is to balance exploration of the multiple degrees of freedom and exploitation of known data (i.e., local optimization). A key test is to compare against existing Monte Carlo and genetic algorithm methods already implemented in Open Babel.
In many molecules, the degrees of freedom (dihedral angles) are non-independent, so detecting correlations between dimensions, dimensional reduction, etc. should likely improve performance. Combining data science and machine learning techniques may allow the code to detect such conditions based on the molecular structure (i.e., this is not a completely black-box optimization - we know some of the physics involved).
Prerequisites: Experience in C++ or Python. Knowledge of data science or statistics (e.g., Bayesian inference, data mining) is ideal.
Mentor: Geoff Hutchison (geoffh at pitt dot edu)
cclib Project Ideas
cclib is an open source library, written in Python, for parsing and interpreting the results of computational chemistry packages. The goals of cclib are centered around the reuse of data obtained from these programs and contained in output files.
Project: Advanced Analysis of Quantum Chemistry Data
Brief explanation: Implement additional analysis and quantum calculation methods, including ELF (electron localization function), AIM (Bader's Atoms-in-Molecules) techniques, and/or DDEC6 atomic charges.
Expected results: The current cclib library offers some calculation methods, including fragment analysis and some charge models. Many modern analysis techniques exist to partition electron density, including computing gradients, Laplacians, ELF (electron localization function), Bader's AIM analysis, etc. Similarly multiple partial charge assignment methods exist and can be implemented, including DDEC6.
Suggested Readings:
Prerequisites: Experience with Python and linear algebra (including numpy, scipy), some experience with numerical methods suggested.
Mentor: Geoff Hutchison (geoffh at pitt dot edu)
Project: Refactor parsers
Brief explanation: The main extract() functions in parsers are long and should be split into smaller functions for maintainability.
Expected results: Ensure test coverage of cclib prior to refactoring, propose a few different approaches and discuss with cclib team, and implement the best proposal. Ideally new functions are consistent across parsers and associated docstrings can be used for keeping documentation up-to-date.
Prerequisites: Experience with the Python.
Mentor: Adam Tenderholt (atenderholt at gmail dot com) and Karol Langner (karol.langner at gmail dot com).

Brief explanation: There are tens or hundreds of thousands of computational chemistry results available online - let's mine them!
Expected results: Build a crawler that identifies and indexes computational chemistry content online, and provides the ability to extract data with cclib.
Prerequisites: Experience with Python, and ideally familiarity with computational chemistry and web indexing.
Mentor: Karol Langner (karol.langner at gmail dot com).
Project: Machine learning applied to parsing computational chemistry output
Bried explanation: Can we teach a machine to parse computational chemistry logfiles at least as well as cclib already does? What machine learning approach here would be most appropriate? Is it useful to include prior (chemical) knowldedge or soft constraints to guide parser learning?
Expected results: Identify and implement a machine learning pipeline that attempts to reproduce or complement cclib's various parsers.
Prerequisites: Experience with Python, machine learning, and ideally familiarity with computational chemistry.
Mentor: Karol Langner (karol.langner at gmail dot com).
3Dmol.js Project Ideas
3Dmol.js is a modern, object-oriented JavaScript library for visualizing molecular data that is forked from GLmol. A particular emphasis is placed on performance.

Mentor: David Koes (dkoes@pitt.edu)
Project: Google Cardboard for 3Dmol.js
Brief explanation: Implement low cost virtual reality visualization using Google Cardboard
Expected results: [Google Cardboard https://en.wikipedia.org/wiki/Google_Cardboard] is a VR experience using commodity smartphones and either a paperboard/cardboard mount or an inexpensive pre-made mount. The project would produce an implementation using the Cardboard SDK for 3Dmol.js, allowing both individual VR use and synchronized classroom use (e.g., one "guide" and multiple synchronized viewers).
Prerequisites: Experience with JavaScript and client-server programming, some experience with OpenGL/WebGL ideal, but not necessary.
Mentor: David Koes l (dkoes@pitt.edu)
RDKit Project Ideas
The RDKit is a BSD licensed open source cheminformatics toolkit written in C++ with wrappers for use from Python, Java, and C#. The RDKit also provides "cartridge" functionality that allows chemical searching in the open-source relational database PostgreSQL.
Project: Create a generalized fingerprinting function
Brief explanation: The RDKit provides access to a broad range of fingerprints but the interface for accessing them is complex, with multiple functions taking variable parameters. The idea here is to implement a significantly simpler, yet more flexible, method for generating fingerprints. We'll borrow ideas from two published papers while doing this: http://pubs.acs.org/doi/abs/10.1021/ci100062n and http://dx.doi.org/10.1016/j.jmgm.2010.05.008
Expected results: A C++ implementation of the new fingerprinting functionality along with a robust set of test cases. Wrappers for the functions so that it is accessible from within the Python and Java wrappers as well as the PostgreSQL cartridge.

Prerequisites: C++
Mentor: Greg Landrum (greg.landrum at t5informatics dot com)
Project: RDKit - OpenMM Integration
Brief explanation: OpenMM (http://openmm.org/) is a high-performance toolkit for force-field based molecular simulation that includes GPU and CPU support. The goal of this project is to make it easy to use OpenMM force fields to minimize the energies of or perform molecular dynamics calculations on RDKit molecules.
Expected results: C++ functionality allowing RDKit molecules to be sent to OpenMM for minimization and/or to perform molecular dynamics. A robust set of regression tests for this functionality. Python wrappers around the new functionality. A stretch goal could be to complete the MMFF94 implementation described by Paolo Tosco at the 2016 RDKit UGM (https://github.com/rdkit/UGM_2016/blob/master/Presentations/PaoloTosco_OpenMM_RDKit_integration.pdf).
Prerequisites: C++ and some Python
Mentor: t.b.d.
MSDK / MZmine Project Ideas
Mass spectrometry is an analytical technique that measures the mass of small molecules with high precision. The data coming from mass spectrometry instruments is complex and multi-dimensional. Mass spectrometry development kit (MSDK [1]) is a Java library of algorithms for processing such mass spectrometry data. The goals of the library are to provide a flexible data model with Java interfaces for mass-spectrometry related objects (including raw spectra, processed data sets, identification results etc.) and to integrate the existing algorithms that are currently scattered around various Java-based graphical tools. MZmine [2] is an open-source software for mass-spectrometry data processing. A new version, MZmine 3, which is currently under development, is based on JavaFX for GUI and on MSDK for data processing algorithms.
Project: MSDK - Feature Detection
Brief explanation: Provide a native Java implementation of some popular LC-MS feature detection algorithms from the R world (centWave, massifquant, CAMERA, etc.) [3]. Further development of ADAP-3D module [4] for intelligent, parameter-less feature detection.

NWChem Project Ideas
NWChem is widely used open-source computational chemistry software ([12]) that tackles a wide variety of scientific problems.
Project NWChem-JSON
Brief explanation: Expansion of JSON capabilities in NWChem to plane wave DFT dynamics and molecular dynamics.
Expected results: Expanding JSON output generator in the NWChem source to include plane wave DFT dynamics and classical molecular dynamics capabilities. In addition the "Python NWChem output to JSON converter" needs to be expanded to include these capabilities. The latter strongly overlaps with cclib's project ideas for building a complete set of Python parsers. Questions as to handle large data structures in conjunction with JSON need to be addressed.
Prerequisites: Experience with Fortran90 and Python
Mentor: Bert de Jong (wadejong at lbl dot gov)
Project NWChem-Python-Jupyter Interface
Brief explanation: Exposing and binding NWChem data structures and computational APIs to Python and utilize those in Jupyter notebooks
Expected results: NWChem currently has a very limited interface with Python. But, more and more developers are using platforms such as Python to sandbox new theories, methods and algorithms. In addition, the extended Python interface could be integrated into a Jupyter notebook. A full Python interface needs to be developed for the NWChem software suite.
Prerequisites: Experience with Fortran and Python
Mentor: Bert de Jong (wadejong at lbl dot gov)
JSON-LD for Chemical Data
Brief explanation: Transforming NWChem and Chemical JSON formats to JSON-LD
Expected results: Refactoring NWChem JSON and Chemical JSON formats to utilize JSON-LD. Currently the JSON documents that are created are single dense objects, even though they could be handled as linked objects. This transformation will enable the generated computational data and objects to be more naturally aligned with triple-stores and knowledge graphs when connecting with experimental data.
Prerequisites: Experience with Python and JSON-LD
Mentor: Bert de Jong (wadejong at lbl dot gov)
DeepChem Project Ideas
DeepChem aims to provide a high quality open-source toolchain that democratizes the use of deep-learning in drug discovery, materials science, quantum chemistry, and biology.
Project: Transfer Learning Framework
Brief explanation: Create easy to use tools for common transfer learning scenarios.
Expected results: ChemNet discusses a powerful model independent transfer learning protocol. We would want to reproduce the results, and be able to apply the transfer learning protocol to arbitrary TensorGraph models. Jupyter notebook tutorials and blog posts will be expected over the course of the summer.
Prerequisites: Python, Tensorflow
Mentor: Karl Leswing (karl dot leswing at schrodinger dot com)
Project: Data Interfaces
Brief explanation: Transition deepchem.data.Dataset to tf.data.
Expected results: DeepChem data objects were created before tf.data existed. We need to make our existing Featurizers, Transformers, and Models work over tf.data objects. Jupyter notebook tutorials and blog posts for how to use the new improved interfaces.
Prerequisites: Python, some Tensorflow
Mentor: Karl Leswing (karl dot leswing at schrodinger dot com)
Project: Model Visualization
Brief explanation: Node Importance Visualizations from Graph Models
Expected results: An argument often used against deep learning methods is that they are not understandable. This project would be to implement visual neural graph fingerprints into DeepChem. Stretch goals would be to implement DeepLift or masking techniques for atom level visualizations.
Prerequisites: Python, Tensorflow, rdkit
Mentor: Karl Leswing (karl dot leswing at schrodinger dot com)
Project: Imaging Tools
Brief explanation: Enable chemical image segmentation and property prediction.

Mentor: Bharath Ramsundar (bharath at datamined dot io)
Miscellaneous Project Ideas
These ideas would likely benefit two or more projects.
Project: Utilizing Virtual Reality in Chemistry Visualization and Modeling
Brief explanation:' Develop a VR application or library that can be used to visualize molecular structures, possibly manipulate them.
Expected results: A VR application or library that can be integrated in one of the apps above, focused on molecular structure modeling. The target is both scientific applications and an educational component. If time permits, development of an interface that allows users to manipulate the structures and get a realtime response (using fast molecular force-fields to compute responses) would be a stretch outcome.
Prerequisites: Python, C++, VR SDK experience would be nice.
Mentor: Bert de Jong (wadejong at lbl dot gov)
Project: GPU Accelerated Calculation of Molecular Surfaces and QM Data
Brief explanation: Leverage generic GPU/CPU language (e.g., OpenCL or CUDA) to efficiently generate molecular surface data, including as molecular orbitals or electron (spin) density. This may include methods to approximate the molecular surface using compressed forms (e.g., Gaussian spheres). Current code uses multiple CPU cores, but competing codes can produce near-instantaneous rendering using OpenCL: http://www.kieber-emmons.com/Lumo/) Similar code exists in VMD.
Additional performance improvements may come through efficient surface generation techniques used in other work (e.g., using the Euclidian Distance Transform).
Expected results: Generate appropriate kernels that can be used in any language that supports OpenCL (C, C++, Python, etc.) across multiple platforms.
Prerequisites: General programming experience, and ideally experience in chemistry and matrix manipulations.

Mentor: Geoffrey Hutchison (geoffh at pitt dot edu) and Adam Tenderholt (atenderholt at gmail dot com)
Project: OneMol: Google Docs & YouTube for Molecules
Brief explanation: There is a huge need in the research community for improved collaboration tools on web and desktop. OneMol will provide an open API for collaborating on molecular data that both Avogadro and 3Dmol.js will support as reference implementations. OneMol compliant applications will be able to manipulate and view molecular data in real time so that changes made by one client will be propagated to other clients.
File-sharing is a means for sharing data, but it does not share real-time interactions; each user’s data exists in its own isolated environment. Screen-sharing provides a common viewpoint for all participants, but allowing others to interact with the data requires granting access to the host workstation. This approach is needlessly inefficient for the task of collaborating on molecular data, and this inefficiency introduces scalability issues. For example, a simple rotation necessitates a full screen update when the fundamental change in state was a simple change in viewing angles.
The OneMol framework consists of three main components: a client module, embedded in a molecular viewer; a facilitator module that enforces a consistent viewer state between all the clients; and a storage module that stores the raw molecular data. All three modules may coexist on the same machine within the same application. However, we anticipate a more common modality will be to use a publicly hosted facilitator server, since this simplifies network connectivity in the face of firewalls and network address translation.
Expected results: Prototype web services to allow web and/or desktop collaboration using 3DMol as a viewer, likely integrating with existing storage systems (e.g., MongoChem or PQR).
Prerequisites: Experience with scripting, and web services. Interest and experience with databases like MongoDB or DSpace very helpful.
Mentor: David Koes (dkoes@pitt.edu) or Geoffrey Hutchison (geoffh at pitt.edu)
Project: YAeHMOP as a library
Brief explanation: YAeHMOP (https://github.com/greglandrum/yaehmop and http://yaehmop.sourceforge.net/) is an open-source package of tools for doing extended Hueckel calculations on molecules and crystals. The software was developed as a series of command line tools that expect to read and write from files. After some years of obscurity, YAeHMOP has recently attracted attention as a plugin for Avogadro. The goal of this project is to modernize aspects of YAeHMOP and make the core computational functionality accessible as a library.
Expected results: A library that is callable from C/C++ allowing the construction of an input molecule/crystal, specification of computational parameters, execution of a calculation, and capture of results. Ideally this will include a modernization of the pieces of the code that still rely on f2c-translated Fortran77 code: the eigenvalue solver can likely be replaced with eigen without too much effort; the functionality to calculate STO integrals will need to be re-written based on the original f77. The library should also include a robust set of regression tests. Stretch goals would be adding Python wrappers to the library and/or creating an RDKit plugin for it.
Prerequisites: C/C++
