| Pitfall | Consequence | Solution | |---------|-------------|----------| | Forgetting to merge non-polar hydrogens | Incorrect torsion tree, missing polar H | Always use Merge Non-Polar | | Not removing water molecules | False positive hydrogen bonds | Delete waters unless structurally critical | | Using default grid center without inspection | Docking into irrelevant region | Visually verify binding site using ADT’s 3D view | | Too few GA runs (e.g., <10) | Poor sampling reproducibility | Use ≥50 runs for AutoDock 4; for Vina, set num_modes=20 | | Neglecting to set torsions for flexible side chains | Missed induced fit effects | Use flexible residues feature (Advanced Docking) | | Saving PDBQT with spaces in filenames | AutoGrid/AutoDock errors | Use underscores, no spaces |

Next, she turned to her candidate ligand, a small molecule she hoped would be the cure. In ADT, she defined its , identifying which bonds could rotate and twist—like checking if a key could bend to fit a tricky lock. She saved both files in the essential .PDBQT format , the specialized language AutoDock speaks. autodock tools

ADT remains the best choice for small-to-medium projects requiring visual feedback and educational use. For high-throughput virtual screening (>10,000 ligands), command-line Vina with custom scripts is superior. ADT remains the best choice for small-to-medium projects
