Partial Atomic Charges for Porous Materials based on Graph Convolutional Neural Network (PACMAN)

PACMAN

A Partial Atomic Charge Predicter for Porous Materials based on Graph Convolutional Neural Network (PACMAN)

Usage

from PACMANCharge import pmcharge
PACMaN.predict(cif_file="./test/Cu-BTC.cif",charge_type="DDEC6",digits=10,atom_type=True,neutral=True)

• cif_file: cif file (without partial atomic charges) [cif path]
• charge-type (default: DDE6): DDEC6, Bader or CM5
• digits (default: 6): number of decimal places to print for partial atomic charges. ML models were trained on a 6-digit dataset.
• atom-type (default: True): keep the same partial atomic charge for the same atom types (based on the similarity of partial atomic charges up to 2 decimal places).
• neutral (default: True): keep the net charge is zero. We use "mean" method to neuralize the system where the excess charges are equally distributed across all atoms.
