OK, Phil, got your other message... Right -- JME makes some assumptions here -- for example, if you have a CH2 group and indicate one of the H atoms as UP with a wedge, JME will assign that to be a stereocenter even though it is not. One could test for that, of course, but what about 2 CH3 groups? Same idea. So an instructor would want make sure the key is "normal" and does not show more stereochemistry than there is. It won't matter what the student writes -- as long as the key does not show stereochemistry where there is none.
There was a problem with DOWN bonds disappearing when going to Jmol 2D->3D. I've got that fixed now. On Wed, May 12, 2010 at 8:54 PM, Philip Bays <pb...@saintmarys.edu> wrote: > OK.
