Working on complex molecular systems often means juggling dozens of visualization states, selections, and scripts in SAMSON. Setting up a view, applying the right model to a ligand, or cleaning up water molecules can take up valuable time—especially when repeated…

When modeling protein conformational transitions, a common source of frustration is making sure the start and goal conformations are properly set up in the simulation environment. If these aren’t prepared correctly, everything from calculations to visualization can fail or produce…

Creating carbon nanotube (CNT) models often requires navigating parameters, scripting input files, or searching through existing structures. For molecular designers and simulation researchers, this can slow down workflow, especially when trying to design specific geometries for mechanical or transport studies.…

When you’re building animations of molecular simulations or presentations, one common experience is realizing that you’ve created a beautiful final animation—only to discover that you don’t have an exportable trajectory of the structures along the way. For many modelers, it…

Designing custom polymers often starts with building blocks: monomers. But if you’ve ever spent hours manually assembling repeat units just to test a new polymer idea, you’re not alone. Many molecular modelers face the tedious process of building polymers atom…

When working with molecular simulations in GROMACS, setting up custom index groups can be a source of both power and confusion. Many users need to define custom atom groups for pulling, restraints, or detailed analysis, but the process can feel…

Working on a molecular simulation in solution? If the system you’re modeling is approximately spherical—like a protein, micelle, or nanoparticle—you might be wasting compute time without realizing it. Let’s talk about unit cell shapes and how your choice impacts performance…

When creating molecular presentations or educational visualizations, small movements can make a big difference. One recurring challenge molecular modelers face is how to add subtle, dynamic motion to molecular structures in a way that enhances viewer understanding without overwhelming the…

One of the recurring challenges in cheminformatics and molecular modeling is converting a simple SMILES string into a realistic 3D molecular structure. For many modelers, this means juggling scripts, toolkits, or web services — often repeating the same task across…

Anyone who has worked with molecular modeling knows the frustration of incompatible file formats. You might receive data in PDB format from a colleague, simulate a system in LAMMPS which outputs a DAT file, or need to visualize a CIF…
