See tutorial B4 for instructions on building libraries for molecules not in
the standard database. You can't just open an arbitrary mol2 file in xleap --
running antechamber is generally needed.
You should also check the link on the Amber web site for "modified nucleosides
for RNA". This site has lots of anticodonloop nucleosides; even if it doesn't
have exactly the one you need, it may get you close.
