Re: [AMBER] update_amber script confuses Amber versions

Ah, I see now where I went (horribly, horribly) wrong. I did put
AmberTools13 into the Amber11 directory (in a misguided attempt to keep all
"Amber Stuff" neatly in one place), not realizing the necessity of keeping
the two apart. Thank you, Jason and David, for your amazingly fast replies
and your sage advice.

Hope all is well with everyone.

Let me add just one other possibility: you don't have an update_amber script
in your amber11 directory, but you *do* have an update_amber script in your
path (somehow). So, be sure that your $AMBERHOME environment variable
to a directory tree headed by "amber11"; look in the $AMBERHOME directory to
see if there is really an update_amber script there. As Jason already
out, it would require some unusual combination of events for that to happen,
since the update_amber script is a fairly recent addition.
