About The Project

chempp [kem-pee-pee], is a large scale concurrent chemical search engine using RDKit cartridge, Oat++ and native Postgres & C++ features.

Built With

• Oat++
• PostgreSQL RDKit cartridge
• PostgreSQL
• Special mention to Arthur Farias for his very well crafted url encoding/decoding C++ gist

Installation

Prerequisites

• Knowledge of what a SMILES is in chemistry
• Knowledge of what a SMARTS is in chemistry
• Git
• Docker and Docker-Compose

Install steps

Clone the project

git clone https://github.com/MichelML/chempp.git && \
cd chempp

Then, start the db and fill it with molecules. You have two options:

Option 1 - Small Database of 1000 molecules

docker-compose up -d db && \
docker-compose exec db bash -c "SMALLDB=1 /utility/populate_db.sh"

Option 2 - Large database of ~3M compounds

docker-compose up -d db && \
docker-compose exec db bash -c "/utility/populate_db.sh"

Warning: This command will take a while because it inserts ~3M rows in the db and creates indexes to perform efficient searches, a rough estimate being between 15 minutes and an hour.

Lastly, start the chempp service:

docker-compose up service

Once these commands are ran, you are ready to test the endpoints at http://localhost:8000/swagger/ui .

Usage

See usage through Swagger demo here https://drive.google.com/file/d/1FKh3-N4KWvVEz7NPFmMDALWu-BzYbaHP/view?usp=sharing .
