Compiler for the COlleCtion of Open NatUral producTs (COCONUT)

This compiles is designed to read molecules from various file types (SMILES, SDF, MOL, csv, tsv), check them for errors and connectivity, compute a large number of molecular parameters and properties, and store everything in a Mongo database. Unless you want to modify the code, we recomment using the compiled JAR that can be downloaded here: https://zenodo.org/record/3695455

System pre-requisites:

• MongoDB installed and accessible by the default (27017) port on localhost
• Java minimum 8 version installed

Load COCONUT

You can download the latest version COCONUT from ZENODO (https://zenodo.org/record/3688734). In case you want to explore the whole database in MongoDB, you can load the downloaded dataset dump as following:

unzip COCONUTv2.zip
cd COCONUTv1/COCONUT/
mongorestore --db=COCONUT --noIndexRestore .

Note that for system compatibilities reason, it is better to restore the database without the indexes (hence the "noIndexRestore" option). However, seen the size of the dataset, we suggest to add the indexes as following:

mongo
use COCONUT
db.sourceNaturalProduct.createIndex( {source:1})
db.sourceNaturalProduct.createIndex( {simpleInchi:1})
db.sourceNaturalProduct.createIndex( {simpleInchiKey:1})
db.uniqueNaturalProduct.createIndex( {inchi:1})
db.uniqueNaturalProduct.createIndex( {inchikey:1})
db.uniqueNaturalProduct.createIndex( {smiles:1})
db.uniqueNaturalProduct.createIndex( {clean_smiles:1})
db.uniqueNaturalProduct.createIndex( {molecular_formula:1})
db.uniqueNaturalProduct.createIndex( {name:1})
db.uniqueNaturalProduct.createIndex( {coconut_id:1})
db.fragment.createIndex({signature:1})
db.fragment.createIndex({signature:1, withsugar:-1})

Execution options

Run COCONUT compilation from scratch

java -jar coconut-0.0.1-SNAPSHOT.jar ~/Projects/NP/COCONUT/data ~/Projects/NP/COCONUT/sm/sm.tsv ~/Projects/NP/COCONUT/fragments/fragment_without_sugar.txt ~/Projects/NP/COCONUT/fragments/fragment_with_sugar.txt &

Re-run COCONUT to recompute missing molecular features

java -jar coconut-0.0.1-SNAPSHOT.jar recomputeMissing &

Run only similarity calculation

The provided script also computes similatiry between molecules in COCONUT. This step requires a large amount of memory (this will be optimized in the future) and might need a separate calculation.

java -Xmx12288m -jar coconut-0.0.1-SNAPSHOT.jar runOnlySimilarity &

Run only addition of synthetic molecules

Synthetic molecules (SM) are required for a large number of comparisons with NPs (for example a re-calculation from scratch of NP-likeness score). You need to provide your own dataset of synthetic molecules (SM), we suggest using the ZINC15 dataset. Note that not adding any SM will not affect COCONUT, unless there is a need of re-calculating the NP-likeness score from scratch.

java -jar coconut-0.0.1-SNAPSHOT.jar onlyAddSM ~/Projects/NP/COCONUT/sm/sm.tsv & 

Run only CNPid calculation

In case you need to produce your own CNPid (COCONUT NP identifiers) - not recommened.

java -jar coconut-0.0.1-SNAPSHOT.jar addCNPid  &
