Placing lipids around a protein is a deceptively fiddly modeling task. A layer that is too small can crowd the structure; placing molecules without accounting for the protein can create overlaps. And if the protein and lipids are oriented differently,…

A familiar interruption in molecular modeling is not always a difficult scientific question. Sometimes it is the small task that breaks your concentration: finding the right command, selecting a particular group of atoms, changing a representation, or repeating a few…

A common frustration in molecular modeling is having two structures that represent the states you want to connect, but do not line up neatly as endpoints for a transition-path calculation. They may differ in residue count or structure details. A…

A ligand’s bound structure shows where it sits, but not how it might leave. For molecular modelers, exploring that exit can be difficult: the ligand needs to move through a crowded protein environment, and the surrounding structure may need to…

When you open a molecular modeling platform, the first obstacle is not always the molecule. It can be finding the right place to look: the 3D view, the structure tree, an object’s parameters, or the record of what you just…

When a molecular system is ready for simulation, a steep energy curve can feel reassuring. But a plot that appears to settle down does not, by itself, tell you whether the structure is ready for equilibration. Energy minimization is meant…

When preparing a molecular walkthrough, a camera move can be harder to manage than it first appears. Shift the view too little and the scene feels static; shift it without preserving the framing and the structure you want people to…

A molecular dynamics workflow can be ready to go and still hit a familiar obstacle: the system is too large, or the next simulation stage is too demanding for your local machine. Moving a job to the cloud can help,…
