A Practical Guide to WHAM-Based PMF Analysis in GROMACS Wizard

Computing the Potential of Mean Force (PMF) is a critical task in molecular modeling, especially when investigating molecular interactions and energetic landscapes. However, running umbrella sampling simulations is only half the job—getting accurate PMF results from the output can be…

Breaking and Making Bonds while Simulating Molecules with IM-UFF

In traditional molecular modeling workflows, editing structures often means stopping the simulation, changing the topology manually, and restarting the process. This interrupts modeling intuition and introduces friction, especially during rapid prototyping or educational demonstrations. Wouldn’t it be more natural to…

Filtering Molecular Bonds by Type in NSL

When you’re working with complex molecular structures, isolating specific types of chemical bonds can be critical for both analysis and visualization. Whether you’re identifying aromatic interactions, highlighting hydrogen bond patterns, or preparing data for simulation, having a fast and flexible…

No Admin Rights? No Problem: Installing SAMSON Seamlessly

If you’re a molecular modeler working in a restricted computing environment—such as a university lab or a corporate workstation—you’ve likely had this happen: you find a tool that looks ideal for your needs, but it requires administrative privileges to install.…

Building Lipid Bilayers Around Proteins in SAMSON

Adding lipid bilayers around membrane proteins is often a crucial step in setting up biologically relevant molecular dynamics simulations. But manually constructing these bilayers can be a tedious and error-prone task, especially when trying to avoid overlaps or ensure correct…

Quickly Filter and Control Light Nodes in SAMSON Using the NSL

If you’re designing molecular scenes in SAMSON and using lighting to enhance visualization—whether for rendering presentations or exploring simulation results—you’ve likely faced the frustration of managing multiple light sources. As scenes get more complex, you’re forced to click light by…
