POSIT - Ligand Guided Small Molecule Posing

POSIT - Ligand Guided Small Molecule Posing is a tool to pose multiple ligands against multiple receptors. POSIT works best when fitting to a collection of co-crystal ligands, however, it can also be used for single ligand targets. Each pose that POSIT generates is analyzed with a simple heuristic and marked with a probability.

The minimal inputs into POSIT are protein receptor(s) and smiles strings of ligand molecules to pose.

Output from the POSIT floe consists of pose structures of the input ligands, associated probabilities, protein-ligand clash information and interaction energies.

Running POSIT with multiple receptors requires careful consideration of the hardwire memory limits. The memory requirement increases with the number of receptors. The default setup is sufficient when the number of receptors is ~100 or less. Please contact support@eyesopen.com for help, is case when you want to run this floe with more receptors than 100.
