I used VMD tool for matching structures without any problem until tried to
fit atom triplets. For these structures the command "measure fit" in a
script produces irrelevant transformation matrix. Program move second
structure far away (to almost infinity) instead of aligning the structures.
Use of graphical RMSD Tool leads to the same result. The structures are
given bellow. I use VMD with WindowsXP. How the problem can be fixed?
