Hi David,

----------------------------------------

A couple other things: can you run MD on atoms of an unknown element as far
as Leap is concerned, i.e. a "?" in the "element" column of the edit atoms
table in Xleap, and what is the "unused" column in that table for? I can't
find any rhyme or reason as to why it is designating some atoms as unused.

Thanks so much
-Tim
