** Warning: No sp2 improper torsion term for OS-H1-CI-CT
atoms are: O5' H5'2 C5' C4'
** Warning: No sp2 improper torsion term for H1-H1-CI-CT
atoms are: H5'1 H5'2 C5' C4'
If I remember correctly, these messages appear whenever an atom has
3 neighbors and no improper term applies. It is suspicious that this
is happening to C5' (the 3rd atom is the central one) - shouldn't it
have 4 neighbors? (O5', H5'1, H5'2, C4') I.e. possibly in one or more
places you are missing H5'1 and in other(s) a bond to O5'.
