Automated typing inference from scratch

Organise a meeting to coordinate efforts.

Full-time person needed – to be discussed further. Work of Josh Fass (Deactivated) and Tobias Huefner may assist here. Owen Madin interested.

Mixture Properties

Binary Mixture Data Feasibility Study

Non-bonded optimization

Driver:Simon Boothroyd
Team: Michael Shirts Owen Madin

Chemical potential-like properties

Non-bonded optimization

Implementation in Evaluator

Need to evaluate the data first (testing needed)

Simon Boothroyd Spinoff (student)

Octanol-water partition coefficients

Implementation in Evaluator

Data needed, harder problem

Simon Boothroyd spinoff (Student)

Data coverage and availability

Feasibility studies

Check the available data and identify missing data points. Worry in the future what to do about it. We will use what we have for Sage.

Ongoing

QM Data Generation

QM dataset selection (training data)

Need to expand to benchmarking set.

David Mobley Jessica Maat (Deactivated) Hyesu Jang

Benchmarking/re-evaluating our choice of QM theory

(Optional) QC Dataset submission infrastructure

Test of the whole torsiondrive. Keep within 10-50 torsiondrives. More is better.

Hyesu Jang lead; Lee-Ping Wang

Hyesu Jang also leading molecule set selection with help from Jessica Maat (Deactivated) and Victoria Lim (Deactivated)

Protomer/tautomer enumerated molecules

QM level of theory validation (QMLoTV)

Protonation/tautomer enumeration integration (Joshua Horton doing OE version in toolkit; there’s currently no good protonation state enumeration with RDKit – see

Data on molecules with nonzero formal charges

QM level of theory validation (QMLoTV)

(Optional) QC Dataset submission infrastructure

Enamine REAL fragment coverage

Automated fragmentation integration (Joshua Horton

Ligand Expo fragment coverage

Automated fragmentation integration (Joshua Horton

Ligand Expo has higher priority than Enamine Real.

Richer torsion data for WBO fitting

WBO torsion implementation

(person needed to continue work of Chaya Stern (Deactivated) )

Biopolymer data selection (ensure sidechain data is available in QCA)

ASAP

David Cerutti (Deactivated)

Biopolymer data computation

(Optional) QC Dataset submission infrastructure

David Cerutti (Deactivated)

More efficient torsion sampling with less grid points during scan

Fitting

Addition of new parameters – manually fixing problems

Ongoing

LJ refitting (Sage)

Non-bonded optimization

Simon Boothroyd and Owen Madin

WBO refitting (Sage)

More torsion data

WBO torsion implementation

Implement what Chaya has already done. As soon as infrastructure is ready.

After May meeting

Late 2020 (Sep 2020)

Jessica Maat (Deactivated) Hyesu Jang Someone else to continue where Chaya left it off

BCC refitting

LJ refit

Patterns for BCCs; could start with something simple like bond SMARTS.

ChargeIncrementModel implementation (early May)

Person needed (

David Mobley can help

Study how to set prior widths and weights for different sorts of data during FF optimization

Lee-Ping Wang Hyesu Jang Spinoff?

Value of data generated “incidentally” during torsiondrive in fitting, e.g. optimization snapshots, gradients, energies (low control over these data points)

Some parts of Bespoke workflow

Joshua Horton

Benchmarking

Small reference system for fast testing of FE infrastructure – 5-10 small reference systems, possibly subset of SAMPL challenges, for comparison of different free energy methods to avoid using large P-L systems for test calculations

Should use SAMPLing challenge systems plus a couple more similar ones.

ASAP

Benchmarking/re-evaluating our choice of QM theory

Lee-Ping Wang

CCDC data selection/release

Create a list of tests to judge the “quality” of biopolymer FF with our scientific advisory board

Organise the meeting with our IAB, invite to May meeting

Biopolymers

Which quantum method should we use for biopolymers (should it be the same as small molecules)?

QM benchmarking study

Charges

GCN charge model

In a few steps:

• conda-installable tool to assign charges

• integration of tool into OFFTK under ChargeIncrementModel keyword (and exposure of relevant keywords)
