Posit

Generates relaxed high probability poses for ligands that are
analogs of the ligand in the receptor. This cube is suitable for pose generation when working with multiple receptors.

Calculation Parameters

  • Allowed clash type (string) : Types of clash acceptable between protein and ligand in the pose
    Default: HYDROGEN
    Choices: ANY, HYDROGEN, NONE
  • CPUs (integer) : The number of CPUs to run this cube with
    Default: 1 Min: 1 Max: 128
