I am trying to connect two sugars by glycosidic bond with the following in
the coordinate file:
MODRES GAL A 2 GAL-b-D RENAME
MODRES NAG A 3 NAG-b-D RENAME
LINK NAG A 3 GAL A 2 BETA1-3
Get an error message:
I am reading library. Please wait.
mon_lib.cif
WARNING : link:BETA1-3 is found dist = 1.698 ideal_dist= 1.439
ch:AA res: 2 GAL at:C1 .->Aa res: 3 NAG at:O3 .
ERROR: wrong tree structure .....
IERR = 1
I tried all possible combination for geometric restraints for sugar:
define as in file or by distance with the same result.
Can anybody tell what is wrong?
