Question 1

How to visualize 3D molecules in MolecularGraph.jl?

Accepted Answer

Use the integration with Makie.jl for 3D rendering, as shown in the drawing tutorial. Install Makie.jl separately and follow the examples to export interactive plots in notebooks.

Question 2

MolecularGraph.jl vs RDKit: which is better for drug discovery?

Accepted Answer

RDKit has more features, better optimization, and a larger community in Python. MolecularGraph.jl excels in Julia-native performance and graph theory approaches but lacks RDKit's maturity and extensive tooling.

Question 3

Does MolecularGraph.jl support machine learning for cheminformatics?

Accepted Answer

It calculates descriptors and fingerprints but lacks built-in ML models. You'll need to export data to Julia's ML libraries, which are less developed than Python's alternatives like scikit-learn.

Question 4

How to install MolecularGraph.jl with all dependencies?

Accepted Answer

Use Julia's package manager, but be prepared to handle external libs like RDKitMinimalLib.jl and coordgenlibs. Check the README for system requirements, which may involve manual setup steps.

Question 5

Can MolecularGraph.jl handle large chemical databases efficiently?

Accepted Answer

It supports batch processing via graph algorithms, but performance varies with dataset size. Benchmark against dedicated tools like RDKit for high-throughput screening, as MCS and isomorphism can be resource-intensive.

Question 6

What's the difference between MCIS and MCES in this toolkit?

Accepted Answer

MCIS is node-induced and MCES is edge-induced maximum common substructure, both implemented via clique detection. The tutorials explain how to choose based on topological constraints for similarity analysis.
