Hello,From my experience, those warnings do not need any action. You might however get rid of them by specifying the hybridisation of the new atom types. If you open the leaprc file you use, at the very top there will be a list of atoms and the hybridisation for each (sp3, sp2, etc). Add your atom types and the warning should go away.Cheers Pietro

Thanks a lot!!Best,FabianFabian Glaser PhDHead of the Structural  Bioinformatics section Bioinformatics Knowledge Unit - BKUThe Lorry I.
