I certainly agree that LEaP does not do as well as it should in reading (and I
guess, saving) mol2 files. I'm hoping we can improve this soon; but for now,
it's probably safest to put only single resdiues into mol2 files that are
intended to be used by LEaP. (And, the problems noted above may or may not
have to do with mol2 formats, but may reflect hidden problems in the first
line, in that extracting a piece from a larger unit may not actually work the
way it should...I'll post more when I have a better handle on what is
happening.)

...thanks for the input...dac
