dear amber !

I am trying to fuse the protein to the glycans in xleap using the GLYCAM_06

When I went through the documentation the N -glycosylation site for ASN
residue must be changed to label NLN , I did it.

I tried to build the carbohydrate from the side chain of the ASN , in the
atom ND2 , I am able to build it , but when I saved the parameter file It
says the error in Building topology.

Building atom parameters.
Building bond parameters.
Building angle parameters.
Building proper torsion parameters.
 ** No torsion terms for Os-Cg-Cg-N
Building improper torsion parameters.
old PREP-specified impropers:
 total 364 improper torsions applied
 0 improper torsions in old prep form
Building H-Bond parameters.
Parameter file was not saved.

I feel that the atom type to the atoms should be changed , but i dont know
which type is relevant ( the ND2 type is N so that is saying error )

how to fix this ?

thanks in advance
