GSoC Ideas 2023

Guidelines

Open Chemistry is an umbrella for projects in chemistry, materials science, biochemistry, and related areas. While we have participated in the last few Google Summer of Code programs and will apply again in 2022, there is no guarantee that we will be selected again for GSoC in 2023.

One important factor is that GSoC in 2023 will include both shorter projects (~175 hours) and longer projects (~350 hours). You should consider the appropriate timeline for your project proposal. We have indicated in the project totals where we suggest particular lengths.

Contributors can also decide on the number of weeks (e.g., spreading the project time over multiple weeks).

If you are unsure of the scope of a project, please reach out and discuss BEFORE the proposal deadline.

When possible, submitting drafts a week or more in dance of the proposal deadline is preferred because we can make suggestions towards your proposal.

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!

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 [350 hours]: Scripting Bindings

Brief explanation: Implement an embedded scripting language (i.e., Python) in Avogadro 2

Expected results: Enable an embedded scripting console as well as support for implementing modular extensions (tools, rendering, etc.) in Python. Python bindings exist, using PyBind11 with the new codebase, and the Avogadro 2 core libraries are pip installable. Extending the coverage of the API from the rudimentary parts of core/io would be a good starting point. An ideal solution would connect to PySide, to allow scripting to add UI like menu items, windows, etc. and provide documentation and example scripts. The interface should be maintainable as new classes and methods are added.

Example scripts, documentation, are highly encouraged.

Prerequisites: Experience in C++ and Python, some experience with PyBind11, Qt for Python, PySide suggested.

Mentor: Geoff Hutchison (geoffh at pitt dot edu) or Marcus D. Hanwell (mhanwell at bnl dot gov)

Project [175 hours]: 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.

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 [175 hours]: Integrate CoordGen library

Expected results: Schrodinger has released a BSD-licensed library for 2D chemical structure layout (https://github.com/schrodinger/coordgenlibs) and it has been successfully integrated into RDKit. The student will be responsible for integrating CoordGen into Open Babel. Code will be written in C++.

Mentor: Geoff Hutchison (geoffh at pitt dot edu)

Project [175 hours]: 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 [175 hours]: Test Framework Overhaul

Brief explanation: Automated testing is an important part of maintaining code quality. This project will improve the current testing regime of openbabel.

Expected results: A comprehensive test framework that automates the generation of unit tests for all supported languages and simplifies the creation of new test cases will be implemented. The student will be responsible for choosing the most appropriate framework, porting existing test cases, and expanding the test suite to enhance code coverage.

Prerequisites: Experience in C++. Knowledge of modern software engineering practices or test frameworks is ideal.

Mentor: Geoff Hutchison (geoffh at pitt dot edu), David Koes (dkoes at pitt dot edu), the OpenBabel development community.

Project [350 hours]: Develop a JavaScript version of Open Babel

Brief explanation: Building on existing work, you will use Emscripten to compile the C++ codebase of Open Babel to JavaScript. This will make it easy to write in-browser applications that need cheminformatics functionality.

Expected results: Following from work described in a recent paper (https://pubs.acs.org/doi/abs/10.1021/acs.jcim.7b00434), a JavaScript version of the Open Babel toolkit will be created. The generation of any necessary wrappers should be automated to allow it to track changes in the Open Babel API.

Ideally, the project will adapt a core JavaScript library openbabel.js that allows modules, such as file formats to be imported separately (e.g., smilesformat.js, pdbformat.js, xyzformat.js, etc.)

Prerequisities: Some experience in C++, and also with JavaScript.

Mentor: Geoff Hutchison (geoffh at pitt dot edu)

Project [350 hours]: Develop a validation and standardization filter

Brief explanation: Given a particular molecular structure, can we say how chemically plausible is it, and use this as to filter or warn about problems (e.g., undefined stereo centers)?

Expected results: Given a set of reference structures (e.g. ChEMBL), it should be possible to build a model that can say how normal/unusual a query structure is. For example, given a set of drug-like molecules, a molecule with a ruthenium atom might be considered unusual; or given any set of molecules, a 5-coordinate carbon is unusual.

Such a model could be used as a filter, or as a warning to flag up problematic structures.

Code could be modeled on MolVS using RDKit [[1]]

Prerequisites: Experience in C++ or Python, and an interest in data science or statistics.

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 when stored in program-specific output files.

Project: [175 or 350 hours] Implement new parsers

Brief explanation: There are outstanding issues on GitHub for supporting more programs (e.g. CFOUR, xtb, NBO, GAMESS dat, MRCC, DIRAC), and parsing binary files for various QM programs (e.g. Gaussian, NWChem, and ORCA). There may also be more programs missing that haven't been considered.

Expected results: Implement parsers for one or more new programs/formats, generate test data, and write unit and regression tests for each parser.

Prerequisites: Experience with Python, basic familiarity with computational chemistry programs, and access to the program(s) needed to generate the test data.

Mentors: Eric Berquist (eric.john.berquist at gmail dot com) and/or Shiv Upadhyay (shivnupadhyay at gmail dot com) and/or Adam Tenderholt (atenderholt at gmail dot com) and/or Karol Langner (karol.langner at gmail dot com)

Project: [175 or 350 hours] Implement new bridges

Brief explanation: There are outstanding issues on GitHub for more integrations with external programs (e.g. chemfiles, RDKit) via their Python bindings. There may also be more programs missing that haven't been considered.

Expected results: Implement bridges for one or more new programs, along with writing unit tests and documentation for each bridge.

Prerequisites: Experience with Python and ideally familiarity with the program that is being bridged.

Mentors: Eric Berquist (eric.john.berquist at gmail dot com) and/or Shiv Upadhyay (shivnupadhyay at gmail dot com) and/or Adam Tenderholt (atenderholt at gmail dot com) and/or Karol Langner (karol.langner at gmail dot com)

Project [350 hours]: Implement new methods

Brief explanation: There are outstanding issues on GitHub for more analysis methods being added directly to cclib (e.g. calculating geometric parameters). There may also be other methods that are desirable to include which haven't been considered.

Expected results: Implement one or more new methods, along with writing unit tests and documentation for each method.

Prerequisites: Experience with Python and familiarity with the method(s) being added, depending on the complexity of the method.

Mentors: Eric Berquist (eric.john.berquist at gmail dot com) and/or Shiv Upadhyay (shivnupadhyay at gmail dot com) and/or Adam Tenderholt (atenderholt at gmail dot com) and/or Karol Langner (karol.langner at gmail dot com)

Project [350 hours]: Julia bindings

Brief explanation: The Julia programming language (https://julialang.org/) is growing in popularity for computational chemistry as a language that both production-level computation and analysis can be performed in seamlessly. In order to analyze computational chemistry outputs from traditional programs in Julia, rather than reimplement all cclib functionality in Julia, we should be able to call cclib from Julia directly and reuse its core functionality.

Expected results: Julia bindings to cclib IO functionality and a Julia-native representation of cclib data objects, with each cclib attribute accessible as a native Julia type. The bindings should be available on the default Julia package registry. The remainder of the project is more open-ended, but an example application of using the bindings would be ideal.

Prerequisites: Experience with Python and/or Julia, and ideally some familiarity with important quantities from computational chemistry outputs.

Mentors: Eric Berquist (eric.john.berquist at gmail dot com)

Project [350 hours]: Additional visualization for OpenChemVault

Brief explanation: OpenChemVault (https://github.com/cclib/openchemvault) is capable of parsing output files, storing them, and displaying geometries, but any sort of additional visualization (such as plotting molecular orbitals or spectra) is missing. The capabilities of GaussSum (http://gausssum.sourceforge.net/) are a possible starting point.

Expected results: Implement one or more new visualizations for the OpenChemVault web interface.

Prerequisites: Experience with Python common visualizations that are desirable for computational chemistry outputs. No previous experience with JavaScript is necessary.

Mentors: Eric Berquist (eric.john.berquist at gmail dot com) and/or Shiv Upadhyay (shivnupadhyay at gmail dot com) and/or Adam Tenderholt (atenderholt at gmail dot com) and/or Karol Langner (karol.langner at gmail dot com)

RDKit Project Ideas

The RDKit is a BSD licensed open source cheminformatics toolkit written in C++ with wrappers for use from Python, Java, C#, and JavaScript. The RDKit also provides "cartridge" functionality that allows chemical searching in the open-source relational database PostgreSQL.

Project [350 hours]: Implement Molecular Interaction Fields calculations in the RDKit

Brief explanation: There is an old PR for the RDKit that implements molecular interaction fields: https://github.com/rdkit/rdkit/pull/318. This was never merged because the author ran out of time. At this point a lot of work would be required to update and finish this PR, but the results would be super useful for the RDKit community.

Expected results: A C++ implementation of the GRID calculator code along with a robust set of test cases. Wrappers for the calculator so that it is accessible from within the Python and SWIG (Java and C#) wrappers.

Prerequisites: C++

Our goal is to make programming accessible to chemists and promote precepts of sustainable software development. The two main pieces of the QC-Devs ecosystem are:

HORTON (electronic structure theory): https://quantumelephant.org/
ChemTools (molecular structure and reactivity): https://chemtools.org/

All our repositories are hosted on Theochem organization (https://github.com/theochem) on GitHub.

Project [175 hours or 350 hours]: Visualization of Molecular Structure and Reactivity

Brief Explanation: ChemTools (https://github.com/theochem/chemtools) is a post-processing library for extracting chemical insight from quantum chemistry calculations. Currently, ChemTools relies on Visual Molecular Dynamics (VMD) and Matplotlib for visualization. ChemTools has the functionality to generate visualization scripts for VMD, so the user can easily generate informative plots like iso-surface of electron density colored by electrostatic potential. Visualization of (annotated) molecular structures and molecular structure changes along reaction pathways are also of interest, but the implementations are unpolished.

Expected Results:

175 hours: Add functionality to ChemTools to generate visualization scripts for ChimeraX (https://www.cgl.ucsf.edu/chimerax/). The current functionality for VMD can be used as a template.
350 hours: Add ChemTools as a back-end for SEQCROW (https://cxtoolshed.rbvi.ucsf.edu/apps/seqcrow), a free and open-source bundle (https://github.com/QChASM/SEQCROW) in the ChimeraX toolshed (https://cxtoolshed.rbvi.ucsf.edu/) for building molecules and interacting with the output of quantum chemistry calculations.

Project [175 hours] Molecule Alignment with Procrustes Algorithm

Brief Explanation: Procrustes (https://github.com/theochem/procrustes) is a library for finding the optimal transformation that makes two matrices as close as possible to each other. Permutation Procrustes methods can be used for molecular alignment (J Math Chem (2013) 51:927ΓÇô936). The goal of this progress is to develop a utility that uses the Procrustes package to perform molecular alignment.

Expected Results: An open-source Python software.

Mentors: Fanwang Meng (fwmeng88 at gmail dot com) and Paul Ayers (ayers at mcmaster dot ca).

Project [350 hours]: Faster Molecular Integrals with Density-Fitting

Brief Explanation: GBasis (https://github.com/theochem/gbasis) is a library for evaluating and analytically integrating Gaussian-type orbitals and their related quantities, especially molecular integrals. In many applications, the computational bottleneck is the evaluation of two-electron integrals, as the number of two-electron integrals grows as the fourth power of the basis-set size. By introducing an auxiliary, density-fitting, basis, this power is reduced to the third power of the basis-set size, which in many cases eliminates the computational bottleneck, since there are often other facets of the computation that scale more severely than this. The goal of this project is to implement density-fitting methods into GBasis.

Expected Results:

350 hours: Extension of GBasis to support density fitting. This involves expanding products of basis functions in the auxiliary basis, evaluating 2-electron integrals in the auxiliary basis, and using these two entities to construct molecular integrals more efficiently.

Difficulty Level: Intermediate to Advanced

Relevant Skills: Experience with scientific Python, advanced Numpy, and object-oriented programming.

Mentors: Ali Tehrani (alirezatehrani24 at gmail dot com), Gabriela Sanchez Diaz (sanchezg at mcmaster dot ca), and Paul Ayers (ayers at mcmaster dot ca).

Brief Explanation: The electron pair density represents the probability of observing two electrons at two points in space. It provides key quantitative and qualitative information about electron correlation, as well as qualitative information about chemical bonding and, in particular, about how Lewis structures emerge from quantum mechanics.

Expected Results:

350 hours: To provide a Python function to compute the pair-density using GBasis (https://github.com/theochem/gbasis) as a Python function, starting from wave-function information that is read with IOData (https://github.com/theochem/iodata). Key indicators like the intracule and extracule should be supported.

Difficulty Level: Intermediate

Relevant Skills: Experience with scientific Python, advanced Numpy, and object-oriented programming.

Mentors: Ali Tehrani (alirezatehrani24 at gmail dot com), Gabriela Sanchez Diaz (sanchezg at mcmaster dot ca), and Paul Ayers (ayers at mcmaster dot ca).

Project: [350 hours] Extended Interoperability of Denspart to Open Force Field Software

Brief Explanation: Partitioning a chemical system and its various properties into atomic contributions is not only qualitatively useful for chemical analysis but important for quantitative computational chemistry (e.g., charges in molecular mechanics force fields). This can be done by partitioning the molecular electron density into fuzzy atomic densities using Denspart ( package and class within ChemTools package), but there are alternative approaches based on topological partitioning of molecular density or partitioning of molecular orbitals. The goal of this project is to develop a unified framework determining the molecular contributions of specified atoms and/or functional groups.

Expected Results:

Design a unified DensPart API with interfaces to the two aforementioned packages.
Develop a module for computing various non-covalent force-field energy terms, especially those that are useful for molecular mechanics force field parameterization/development.
Design a framework for enhancing molecular modeling using Denspart (based on quantum chemistry calculations)

Difficulty Level: Intermediate

Relevant Skills: Experience with scientific Python, advanced Numpy, and object-oriented programming, familiarity with quantum chemistry, molecular mechanics, and force-fields.

Mentors: Farnaz Heidar-Zadeh (farnaz.heidarzadeh at queensu dot ca), Toon Verstraelen (Toon.Verstraelen at ugent dot be), and Esteban Vohringer-Martinez (estebanvohringer at qcmmlab dot com).

It also supports a flexible framework for generating input files for various software packages. The goal of this project is to extend the IOData framework to describe a chemical system for molecule mechanics (MM) modeling, specifically in the context of non-covalent interactions of open force-fields.

Expected Results:

Embed a compatible data structure for non-bonded parameters derived from electron density partitioning methods into the IOData framework.
Generate an Open Force Field Toolkit compatible output ()
Extend IOData framework to accommodate bonded parameters to have a full interface for molecular modeling.

Difficulty Level: Intermediate

Relevant Skills: Experience with scientific Python, advanced Numpy, and object-oriented programming, familiarity with molecular mechanics and force-fields.

Project: [350 hours] Deriving Atomic and Bond Properties from Molecule Orbital Partitioning

Brief Explanation: In traditional orbital-based atomic partitioning methods for molecular wavefunctions, one observes that the results are strongly dependent on the molecular basis set, and tend to work poorly for large atom-centered basis sets and be inapplicable to delocalized (e.g., plane wave) basis functions. One way to avoid these issues is using various sorts of quasi-atomic orbitals (QUAOs), including quasi-atomic molecular basis orbitals (QUAMBO), intrinsic atomic orbitals (IAOs), and other choices. Another alternative is to use (approximate) orbital-based equivalencies to spatial decomposition methods like the Hirshfeld or Bader partitioning. The goal of this project is to implement these approaches in the OrbsTools module of ChemTools ().

Expected Results:

Design an API for various quasi-atomic orbital methods and implement QUAMBO, IAO, QUAO and possibly other quasi-atomic orbital methods.
Reenvision the Mulliken and Lowdin atom/bond analysis based thereupon.
Implement the orbital-based partitioning based on an arbitrary spatial partitioning method, the Mulliken and Lowdin atom/bond analysis based thereupon.

Difficulty Level: Intermediate to Hard

Relevant Skills: Experience with scientific Python, advanced Numpy, and object-oriented programming, familiarity with quantum chemistry methods.

Project: [350 hours] Model Hamiltonian (interface to FCIDump and other solid-state codes)

Brief Explanation: In many cases, the true many-electron Hamiltonian is intractable to solve, so model Hamiltonians that capture key features of the physicochemical system qualitatively. Classic examples include the (extended) Hubbard, Ising, and Heisenberg model Hamiltonians. The goal of the package is to build an framework for constructing Model Hamiltonians and outputting them into a format that is conducive to traditional packages for solving the quantum many-body problem.

Expected Results:

1. Provide support for Huckel/Hubbard/PPP parameters for various atom and connectivity types.

2. Write user-friendly APIs for constructing model Hamiltonians of various types: Heisenberg, Ising, generalized Richardson-Gaudin, t-J, and t-J-U-V models.

3. Write utilities to output model Hamiltonians into formats conducive to external programs, including FCIDump and Triqs.

4. Create and write example tutorials.
