Understanding how proteins arrange themselves into larger structures is a recurring challenge in molecular modeling. Whether you’re studying quaternary structures or designing nanostructures, one issue always arises: how to easily visualize the full biological assembly from the asymmetric unit provided…

If you’ve ever run molecular dynamics (MD) simulations with GROMACS, you know how crucial the .mdp file is. It defines all the parameters that control how your simulation behaves—from minimization settings to production dynamics. But editing this file manually can…

If you’ve ever tried protein-protein docking and encountered strange results — unexpected clashes, misaligned complexes, or long computation times — chances are your system wasn’t properly prepared. Protein preparation is foundational for successful docking, yet it’s often overlooked or done…

Color is an essential tool for molecular modelers. Whether you’re communicating structural insights, visualizing properties like hydrophobicity or temperature factors, or simply enhancing the aesthetic clarity of a molecular scene, choosing the right color scheme makes a big difference. But…

Molecular modelers working with large symmetric assemblies—like viral capsids or multi-subunit protein complexes—often face a dilemma: Should I simulate the entire structure, or is there a smarter way? In many cases, the repetitive nature of these biological assemblies means you’re…

When performing covalent docking, one of the most common sources of error stems from improper ligand preparation — especially when working with ligands already covalently bound in crystal structures. By default, automatic preparation tools may fail to reconstruct the originally…

One of the most common setup pains in molecular modeling arises when preparing atomic coordinates along a ligand’s exit or binding path. Whether you’re running free energy calculations, benchmarking enhanced sampling methods, or analyzing transition mechanisms, a clean and flexible…
