Is a GPU required to use this skill?

While DiffDock can run on a CPU, a GPU is strongly recommended. Using a GPU typically provides a 10x to 100x speedup, which is essential for virtual screening of multiple compounds.

Can I run docking using only a protein sequence?

Yes, this skill supports protein sequences by utilizing ESMFold to generate embeddings, allowing for docking even when a high-resolution PDB structure is unavailable.

Does DiffDock predict binding affinity?

No, DiffDock is specifically designed to predict the 3D binding pose and providing a confidence score regarding the structural accuracy. For affinity prediction (ΔG), you should combine DiffDock results with scoring functions like GNINA or MM/GBSA.

What is considered a 'good' confidence score in DiffDock?

Confidence scores greater than 0 are generally considered high confidence. Scores between -1.5 and 0 are moderate, while scores below -1.5 indicate low prediction certainty.
