G-screen

A Scalable Receptor-Aware Virtual Screening through Flexible Ligand Alignment.

Installation

G-screen runs in a virtual environment, and works with Python 3.10+. We recommend using uv to manage the virtual environment. G-screen works with G-align as an extra dependency that need to be installed separately; see below for details.

Python environment

This will create a virtual environment in .venv directory at the project root, and install the required dependencies. G-screen will be installed during this process (in editable mode).

uv sync [--no-dev]

G-align

G-align could be downloaded in a precompiled binary form here, or compiled from source code available on GitHub.

G-align is Linux-only and requires libomp5 to be installed. On Ubuntu, this can be done with:

sudo apt-get install libomp5

G-align must be available in $PATH environment variable for G-screen to work.
