I can't reproduce the problem: the above script works for me, with no errors.
So, we will need some more information:
1. How did you get AT17? e.g. via "update_amber --upgrade"? by downloading
the tar file from the web site? In the latter case, did you un-tar
the file on top of an existing AT16 distribution?
2. What OS, compiler?
3. Double check that "which tleap" returns what you expect; that AMBERHOME
is correctly defined, etc. But I'm grasping at straws here, as you can tell.
If you have access to another computer with AT16 or AT17 installed, you
could see if you get the same failure there. It might be worth doing a
fresh install of AT17 into a new, pristine directory. Or maybe someone on the
list will recognize the symptoms here.
You could try to narrow down the source of the error: if you use
leaprc.DNA.bsc1 is there a different result? How about trying to make a short
peptide?
...good luck...dac
