altmol 0.2.2

No project description provided

altmol

altmol enhances Altair visualizations by integrating interactive 2D molecular structures, leveraging RDKit for rendering. This package is inspired by the capabilities of molplotly.

Installation

altmol can be easily installed using pip or poetry, accommodating both traditional and modern Python workflows.

Using pip

pip install altmol

Using Poetry

If you're managing your project with Poetry, add altmol to your project using:

poetry add altmol

Alternatively, you can manually add it to your pyproject.toml and then install it using:

poetry install

Quick Start

To get started with altmol, ensure you have Altair and RDKit installed in your environment. Here's a simple example to illustrate how to create an interactive scatter plot with molecule visualizations:

import altair as alt
import pandas as pd

from altmol.plot import chem_plot
from altmol.chem import encode_molecules

# URL of the ESOL dataset
url_esol = 'https://raw.githubusercontent.com/deepchem/deepchem/master/datasets/delaney-processed.csv'

# Load your dataset
df = pd.read_csv(url_esol)

# Prepare your data (ensure you have a 'smiles' column for molecular structures)
df = encode_molecules(df, smiles_col_name='smiles', img_format='svg')

x_col_name = "measured log solubility in mols per litre"
y_col_name = "ESOL predicted log solubility in mols per litre"

# Generate and display the interactive plot
chart = chem_plot(
    df,
    x_axis=alt.X(f"{x_col_name}:Q", title="True Log solubility"),
    y_axis=alt.Y(f"{y_col_name}:Q", title="Pred Log solubility"),
    tooltip=[x_col_name, y_col_name],
    selector=False,
    interactive=False,
    title="ESOL Regression"
)
chart.display()
