Hi,
There appear to be syntax errors in several places in your script.
You have "waitfor all" in several places where it doesn't belong, in
particular at the end of some atom selection commands. To debug your
script, you may want to add some calls to "puts" at various points and
that will help you determine where the error occured (after the error(s),
subsequent puts calls won't show up any more).
Cheers,
John Stone
