Evidence-based bioinformatics tutorials, computational biology methods, and practical guidance for molecular research.

Evidence-led articles on scientific methods, reproducible workflows, and software decisions.
Choose a receptor by target state, local pocket evidence, ligand context, and validation. Compare when a holo, apo, AlphaFold, or receptor ensemble best fits a reproducible protein-small-molecule docking campaign.
A docking screen ends with a ranked list, but an assay needs a defensible shortlist. Learn how to combine rank, pose quality, chemical diversity, artifact risk, availability, and controls before experimental testing.
Modern in silico drug discovery is not one algorithm. Learn how target evidence, structure prediction, molecular docking, virtual screening, AI, physics-based refinement, and experiments work as one traceable decision system.
Screen multiple ligands without losing the scientific record. Preserve stable identities, one frozen Vina protocol, failures, ranked poses, exports, and local job history across the batch.
An SDF file can load and still be unfit for docking. Diagnose valence, aromaticity, fragments, stereochemistry, hydrogens, 3D geometry, minimization, and PDBQT failures before AutoDock Vina.
Validate a molecular docking workflow before committing a ligand library: separate pose recovery from screening discrimination, test early enrichment and robustness, and define a defensible go/no-go decision.
Set an AutoDock Vina search space with defensible center and size coordinates, then pair box volume with exhaustiveness, seeds, visualization, and a reproducible validation record.
Prepare receptor and ligand inputs for AutoDock Vina with a reproducible workflow for structure selection, protonation, PDBQT generation, inspection, and preparation records.
Learn what AutoDock Vina affinity, RMSD lower and upper bounds, and mode ranks actually mean—and use a documented c-Abl case to choose poses without relying on score alone.
