I'm using the 3D QSAR pharmacophore generation protocol. I'd like to define a particular feature (PI feature) to be an anchor for all ligands to be mapped. I thought that this could be done by manually adjusting the feature weight but I couldn't quite figure that out. Is there a way to specify that all compounds should map to at least this particular feature, both for model generation and Ligand Pcore Mapping?

Thank you!
