Even more unforunately, it's not possible to access most of the stereo functionality from anything but C++. This is due to the use of nested classes for the stereo config, which we realised after-the-fact is not supported by SWIG. I've tried workarounds but I'm running short of ideas.
Geoff's idea to build the structure based on SMILES seems like a good way to go for the moment. - Noel On 31 July 2012 03:59, Geoff Hutchison <ge...@geoffhutchison.net> wrote: > Unfortunately, Noel (the best person to answer this) is on holiday and > changing jobs shortly.
