CABS-flex standalone 3: an open command-line platform for protein flexibility simulation, peptide structure modeling, and protein-peptide docking
Summary: CABS-flex standalone 3 is an open command-line platform for fast CABS-based coarse-grained modeling of protein flexibility, peptide structures, and global or information-guided protein-peptide docking, coupled with all-atom reconstruction and analysis. The package builds on the established CABS-flex and CABS-dock ecosystem, widely used in structural bioinformatics for protein flexibility simulations and flexible protein-peptide docking. It provides a Python 3 implementation that brings together previous standalone functionality with recent developments in protein flexibility simulation, linear and cyclic peptide modeling, extended reporting and visualization, and deep-learning-based all-atom reconstruction with cg2all. Availability and Implementation: CABS-flex standalone 3 is implemented in Python 3 and is freely available as an open-source command-line package.
