Trehalose

Hi,  I am having trouble minimizing a protein that contains trehalose. Unfortunately, Rosetta does not like trehalose and always deforms it.  

I have no problems with glucose, that's weird because trehalose is a glucose disaccharide.   I am using the flag -include_sugars and the relaxed structure has unrealistic energies because it forces the formation of non-existing bonds.  The main problem is that rosetta assumes it is ->2)-alpha-D-GlucP

Trehalose: C12H22O11  // Iupac: Glc(a1-1a)Glc// Wikipedia: 1-α-Glucopyranosyl-1-α-glucopyranosid

Could you please share some ideas to solve this issue? 

thanks in advance
