Target prep
Load a protein target from the PDB or your own file, check it the way the design tools will, trim it to the chains and residues you need, pick hotspots in 3D, and download the result or send it straight to a design tool. Nothing on this page spends wallet funds or starts a GPU.
Target prep is free with an account.
New accounts start with a $20 wallet balance. Pay by the second of compute. No subscriptions.
