The Package for InfoAlign: Learning Molecular Representation in a Cell

InfoAlign is a package for learning molecular representations from bottleneck information, derived from molecular structures, cell morphology, and gene expressions. For more detailed information, please refer to our paper.

This package uses a pretrained model based on the method described in the paper. It takes molecules as input (e.g., a single SMILES string or a list of SMILES strings) and outputs their learned representations. These molecular representations can be applied to various downstream tasks, such as molecular property prediction.

Installation

Install the package via pip:

pip install infoalign

Usage

Command Line Interface (CLI)

infoalign_pred --input {path_to_input_smiles.csv} 
               --output {path_to_output.npy} 
               --output-to-input-column  # This adds the representation to the input CSV as an additional column

Python API

from infoalign.representer import InfoAlignRepresenter

model = InfoAlignRepresenter(model_path='infoalign_model/pretrain.pt')

# For a single SMILES string
one_rep = model.predict('CCC')

# For a list of SMILES strings
two_reps = model.predict(['CCC', 'CCC'])
