Dear all

I am using tleap and AMBER14SB force filed for my protein. In the leap log I have a lot of lines with warnings for two improper dihedrals involving the N3 atoms

 ** Warning: No sp2 improper torsion term for C8-H-N3-H
        atoms are: CE HZ2 NZ HZ3
 ** Warning: No sp2 improper torsion term for H-H-N3-H
        atoms are: HZ1 HZ2 NZ HZ3

It is safe to ignore them and continue ?

Thanks in advance
