While checking older scripts (that used to work with the 1.1
release), I found that selection algebra does not work properly
anymore -- or at least did change significantly.
Before, if you had defined two objects, say: petite_SU and
grande_SU, you could say:
show cartoon, (petite_SU+grande_SU)
Now, it fails with the error:
PyMOL>show cartoon, (petite_SU+grande_SU)
Selector-Error: Invalid selection name "petite_SU+grande_SU".
( petite_SU+grande_SU )<--
It's quite painful, as it renders obsolete most of my dozens of
Is that a bug, or a documented choice from upstream ?
Meanwhile, I'm downgrading to stable version (means: 1.1).
Can you comment on this please?
